This study provides the cellular and circuit level demonstration of behavioral causality in a neuronal ensemble that encodes a goal location during spatial navigation. Understanding neural underpinnings of ‘where-to-go’ decision has been a long-standing challenge in neuroscience, but little is known about a cognitive unit of “goal location” and no study has directly demonstrated a causal role of such cognitive unit in guiding spatial navigation, suggesting current understanding in spatial navigation remains incomplete.

The Kwon lab delineated neuronal mechanisms of goal-memory and memory-guided spatial navigation in the nucleus accumbens (NAc). The Kwon lab showed how dopamine release in the NAc during positive experience at the goal location rapidly forms a goal memory that is reliably manifested to guide spatial navigation upon needs. The study described how a specific spatiotemporal pattern of dopamine signals shapes NAc neuronal population to encode a spatial goal, and the first time goal-directed navigation is fully reconstituted solely by artificially assembling the goal-memory and motivated behavior together. Results report that NAc memory ensemble can control spatial navigation, suggesting a “modular framework of cognition” in memory-guided behaviors.

The Huganir lab discovered that the presence of calcium-permeable AMPA receptors (CP-AMPARs) contributes to the low feature selectivity of parvalbumin-positive (PV) interneurons across different brain regions and species. The Huganir group found that PV interneurons have a low expression of the GluA2 subunit, leading to an abundance of CP-AMPARs. This low expression is conserved across various species, from ferrets to humans. When CP-AMPARs were replaced with calcium-impermeable AMPARs in PV interneurons, their orientation selectivity in the visual cortex and spatial selectivity in the hippocampus increased. The study also found that inducing CP-AMPAR expression in excitatory neurons, which usually have low CP-AMPAR levels, decreased their orientation selectivity. These findings suggest that CP-AMPARs play a crucial role in maintaining the low selectivity of PV interneurons and that this mechanism is conserved across different species and brain regions.

The lab of Dr. Seth Blackshaw Professor of Neuroscience in the Solomon H. Snyder Department of Neuroscience published a paper in Science that maps out the network of genes that controls the ability of retinal neurons to regenerate from glial support cells. 

The paper’s lead authors, Thanh Hoang and Jie Wang, comprehensively analyzed changes in gene action that occur in retinal glial cells following injury three species – zebrafish, chickens and mice – which differ in their ability to generate retinal neurons in response to injury.  Zebrafish can robustly regenerate neurons, newly hatched chicks can do so weakly and mice, like humans, cannot do so at all.  This study found that retinal glial cells from all three species transition to an activated stage following injury, and that this is required for glia to be able to generate neurons in zebrafish and chicks, but identified a gene regulatory network in mice that actively blocked this process.  By inactivating NFI family transcription factors, which are part of this network, Blackshaw’s group was able to induce mouse glia to generate retinal neurons.  This demonstrates that mammals possess a latent ability to regenerate neurons lost to injury and disease, and that this can be awakened by disrupting genes in this network.  This approach may be useful in cell-based therapies aimed at restoring retinal neurons lost due to blinding diseases.

The lab of Professor of Neuroscience James Knierim in the Zanvyl Krieger Mind/Brain Institute  published a paper in Science that discovered a new role of the Lateral Entorhinal Cortex (LEC)—one of the gateways of information into the hippocampal memory system.  The paper’s lead authors, Cheng Wang and Xiaojing Chen, showed that the LEC encodes experience from a first-person (egocentric) perspective, in contrast to the world-centered (allocentric) coding of place cells, grid cells, and head direction cells.  This discovery supports the idea that the LEC conveys information about the sensory content of an organisms’ experience, which the hippocampus binds within the allocentric maps provided by grid cells and place cells to form the basis of an episodic memory of an event within its spatiotemporal context.

GAMBLING MONKEYS LIKE BIG BETS, STUDY FINDS

Scientists locate area of brain linked to high-risk behavior, a possible step toward improved treatments for destructively risky behaviors in humans
Monkeys who learned how to gamble have helped researchers pinpoint an area of the brain key to one's willingness to make risky decisions.

By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or “ecstasy,” scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree.

A summary of the experiments is published Sept. 20 in Current Biology, and if the findings are validated, the researchers say, they may open opportunities for accurately studying the impact of psychiatric drug therapies in many animals distantly related to people.

Richard Huganir and colleagues report success in using large-scale studies of proteins and high-tech chemical analysis to discover 164 proteins within synapses in mice that outlast neighboring proteins by weeks and months. These stable proteins, they say, may be part of the molecular machinery that governs long-term memory and learning—as well as loss of memory—in all mammals, including humans. A summary of their experiments is published the week of April 2 in the Proceedings of the National Academy of Sciences.

Johns Hopkins researchers report the unexpected presence of a type of neuron in the brains of mice that appears to play a central role in promoting sleep by turning ‘off’ wake-promoting neurons. The newly identified brain cells, located in a part of the hypothalamus called the zona incerta, they say, could offer novel drug targets to treat sleep disorders, such as insomnia and narcolepsy, caused by the dysfunction of sleep-regulating neurons.

It is a puzzle that troubles the field for many years that how pain and itch, two closely related sensations (once thought as one sensation), are differentiated by the nervous systems. Coding of pain and itch are heatedly debated for decades. The current specificity theory suggests that these two kinds of signals are carried by separate pathways, with some interactions, for example pain can inhibit itch and that explains why we all scratch to inhibit pain. It is true in the periphery (our previous study indicate a small population of neurons in the periphery only codes for itch sensation), but a study from our lab suggests that there could be more crosstalk between these two sensations in the central than we expected. People might not notice in real life, but in human psychophysical studies, well-isolated experimental environments, when human subjects are given itchy substances, they typically report intense itch sensations accompanied by minor noxious sensations, such as pricking, stinging and burning. Our new leaky gate model suggest in certain circumstances intense itch signals can trigger minor pain sensations, which can explain such phenomenon.   

Chronic pain is a major health and economic problem worldwide with an estimated prevalence reaching epidemic levels of >25% of the population. For example in the US, chronic pain affects over 116 million adults and costs up to $635 billion annually in treatment and lost productivity. Most drugs on the market for chronic pain have undesired side effects because their targets exist both inside and outside the pain pathways. MrgprX1, a human GPCR, is a promising target of novel pain inhibitors, mainly because of its restricted expression in pain-sensing neurons. Many pharmaceutical companies have conducted drug screens to target human MrgprX1. However, constrained by species differences across Mrgprs, many drug candidates activate MrgprX1 but not the rodent orthologues, leaving no animal model responsive to test the effect on pain in vivo. To overcome the species specificity problem, Xinzhong Dong's lab generated a transgenic mouse line in which they replaced mouse Mrgprs with human MrgprX1. This valuable humanized mouse allowed them to characterize a potent positive allosteric modulator of MrgprX1, ML382. Cellular studies in humanized MrgprX1 mice suggest that ML382 enhances the ability of MrgprX1 to inhibit N-type Ca²⁺ channels via the G_i pathway in nociceptive neurons and block presynaptic terminal transmission in spinal cord. Importantly, ML382 effectively attenuates evoked persistent and spontaneous pain without causing peripheral or central side effects such as itch, motor dysfunction, or reward in the naïve condition.  The group's findings suggest that humanized MrgprX1 mice provide an essential preclinical model and that activating MRGPRX1 is an effective way to treat persistent pain.

The hippocampus is a brain area involved in learning and memory.  The dentate gyrus, a subregion of the hippocampus, may prevent interference between similar memories, but it is unclear how the two main dentate gyrus cell types, granule cells and mossy cells, contribute to this process.  GoodSmith et al. recorded from granule cells and mossy cells as rats explored distinct environments.  Different groups of granule cells fired in different environments, but mossy cells fired in multiple locations in most environments, a feature previously attributed to granule cells. This study resolves a longstanding debate about the firing properties of granule cells, shows that mossy cells have spatial firing, and describes distinct ways in which granule cells and mossy cells can contribute to the ability to distinguish between environments.

Sleep is an essential process that plays a critical role in supporting cognitive functions such as learning and memory consolidation. Synapses in the brain are the structures responsible for forming and maintaining memories. Studying mice, we found that synapses become stronger while the mice were awake and weaker during sleep by removal of the neurotransmitter receptors called AMPA receptors. This is a process called homeostatic scaling-down. Scaling-down during sleep was driven by a protein called Homer1a which builds up in neurons while the mice were awake but is prevented from accessing the synapses until sleep, by the arousal promoting neuromodulator noradrenaline. In this way, the scaling of synapses is limited while awake and engaged as we transition to sleep. Homer1a targeting to synapses was also observed during sleep deprivation, activated by the sleep promoting neuromodulator adenosine. Sleep is well known to enhance memory consolidation whereas sleep deprivation greatly impairs memory formation. Our study suggests that weakening of synapses during sleep contributes to learning and memory, and that if this process is engaged during sleep deprivation memories become lost.

A clump of just a few thousand brain cells, no bigger than a mustard seed, controls the daily ebb and flow of most bodily processes in mammals -- sleep/wake cycles, most notably. Now, Johns Hopkins scientists report direct evidence in mice for how those cell clusters control sleep and relay light cues about night and day throughout the body.
