Activity-Dependent Modulation of Synapse-Regulating Genes in Astrocytes
Astrocytes regulate the formation and function of neuronal synapses via multiple signals, however, what controls regional and temporal expression of these signals during development is unknown. We determined the expression …
Digging behavior discrimination test to probe burrowing and exploratory digging in male and female mice
Digging and burying behavior is often used to test anxiety and repetitive behaviors in mice. Different digging paradigms have been developed and have become popular assays for anxiety, obsessive-compulsive disorder …
Multiple adjoining word and face selective regions in ventral temporal cortex exhibit distinct dynamics
The map of category-selectivity in human ventral temporal cortex (VTC) provides organizational constraints to models of object recognition. One important principle is lateral-medial response biases to stimuli that are typically …
Scientists explore deficits in processing speed in individuals with spinal cord injury
A new study examined the neural mechanisms of higher order cognitive tasks of individuals with SCI. Healthy Aging News — ScienceDaily Read More
by Prolonging the integrated stress response enhances CNS remyelination in an inflammatory environment
The inflammatory environment of demyelinated lesions in multiple sclerosis (MS) patients contributes to remyelination failure. Inflammation activates a cytoprotective pathway, the integrated stress response (ISR), but it remains unclear whether …
Monkey V1 epidural field potentials provide significant information about stimulus location, size, shape, and color.
Brain signal recordings with epidural microarrays constitute a low-invasive approach for recording distributed neuronal signals. Epidural field potentials (EFPs) may serve as a safe and highly beneficial signal source for …
Placebo analgesia does not reduce empathy for naturalistic depictions of others’ pain in a somatosensory specific way
Empathy for pain involves the affective-motivational and sensory-discriminative pain network. The shared representations account postulates that sharing another’s pain recruits underlying brain functions also engaged during first-hand pain. Critically, causal …
Secondary rewards acquire enhanced incentive motivation via increasing anticipatory activity of the lateral orbitofrontal cortex
The motivation to strive for and consume primary rewards such as palatable food is bound by internal satiation and devaluation mechanisms, yet secondary rewards such as money may not be …
