Adaptation maintains population homeostasis in primary visual cortex.
(2013-06)Sensory systems exhibit mechanisms of neural adaptation, which adjust neuronal activity on the basis of recent stimulus history. In primary visual cortex (V1) in particular, adaptation controls the responsiveness of ... -
Assigning the right credit to the wrong action: compulsivity in the general population is associated with augmented outcome-irrelevant value-based learning.
(Nature Research, 2021-11-05)Compulsive behavior is enacted under a belief that a specific act controls the likelihood of an undesired future event. Compulsive behaviors are widespread in the general population despite having no causal relationship ... -
An automated platform for high-throughput mouse behavior and physiology with voluntary head-fixation.
(2017-10-30)Recording neural activity during animal behavior is a cornerstone of modern brain research. However, integration of cutting-edge technologies for neural circuit analysis with complex behavioral measurements poses a severe ... -
Chimpanzee play sequences are structured hierarchically as games.
(2022)Social play is ubiquitous in the development of many animal species and involves players adapting actions flexibly to their own previous actions and partner responses. Play differs from other behavioural contexts for which ... -
Coding of stimulus sequences by population responses in visual cortex.
(2009-10)Neuronal populations in sensory cortex represent time-changing sensory input through a spatiotemporal code. What are the rules that govern this code? We measured membrane potentials and spikes from neuronal populations in ... -
Conserved roles for Hnf4 family transcription factors in zebrafish development and intestinal function.
(2022-11-30)Transcription factors play important roles in the development of the intestinal epithelium and its ability to respond to endocrine, nutritional, and microbial signals. Hepatocyte nuclear factor 4 family nuclear receptors ... -
Distributed context-dependent choice information in mouse posterior cortex.
(2023-01-12)Choice information appears in multi-area brain networks mixed with sensory, motor, and cognitive variables. In the posterior cortex-traditionally implicated in decision computations-the presence, strength, and area specificity ... -
Efficient coding of natural images in the mouse visual cortex.
(Springer Nature, 2024-03-19)How the activity of neurons gives rise to natural vision remains a matter of intense investigation. The mid-level visual areas along the ventral stream are selective to a common class of natural images-textures-but a ... -
The eyes anticipate where objects will move based on their shape.
(2023-09-11)Imagine staring into a clear river, starving, desperately searching for a fish to spear and cook. You see a dark shape lurking beneath the surface. It doesn't resemble any sort of fish you've encountered before - but you're ... -
Gaucher disease protects against tuberculosis.
(2023-02-14)Biallelic mutations in the glucocerebrosidase (GBA1) gene cause Gaucher disease, characterized by lysosomal accumulation of glucosylceramide and glucosylsphingosine in macrophages. Gaucher and other lysosomal diseases occur ... -
NetFACS: Using network science to understand facial communication systems.
(2022-08)Understanding facial signals in humans and other species is crucial for understanding the evolution, complexity, and function of the face as a communication tool. The Facial Action Coding System (FACS) enables researchers ... -
Restoration of vision after transplantation of photoreceptors.
(2012-05-03)Cell transplantation is a potential strategy for treating blindness caused by the loss of photoreceptors. Although transplanted rod-precursor cells are able to migrate into the adult retina and differentiate to acquire the ... -
Standing waves and traveling waves distinguish two circuits in visual cortex.
(2007-07-05)The visual cortex represents stimuli through the activity of neuronal populations. We measured the evolution of this activity in space and time by imaging voltage-sensitive dyes in cat area V1. Contrast-reversing stimuli ... -
The synucleins.
(2002)SUMMARY: Synucleins are small, soluble proteins expressed primarily in neural tissue and in certain tumors. The family includes three known proteins: alpha-synuclein, beta-synuclein, and gamma-synuclein. All synucleins ... -
Transcriptional profiling of zebrafish identifies host factors controlling susceptibility to Shigella flexneri.
(Disease Models & Mechanisms, 2024-01-26)Shigella flexneri is a human-adapted pathovar of Escherichia coli that can invade the intestinal epithelium, causing inflammation and bacillary dysentery. Although an important human pathogen, the host response to S. ... -
Transgenic mice for intersectional targeting of neural sensors and effectors with high specificity and performance.
(2015-03-04)An increasingly powerful approach for studying brain circuits relies on targeting genetically encoded sensors and effectors to specific cell types. However, current approaches for this are still limited in functionality ...
