Single-unit activity in the ventrolateral periaqueductal gray, a brain region implicated in organizing fear output, is found to reflect threat probability, a more versatile threat signal.
A novel statistical algorithm for mining high-dimensional spike train (count) data for significant spatio-temporal patterns reveals new insights into task and brain area dependent functional organization of neural activity.
The combination of intraneural microstimulation and 7T fMRI makes it possible to bridge the gap between first-order mechanoreceptive afferent input codes and their spatial, dynamic and perceptual representations in human cortex.
Techniques are presented to facilitate widespread and standardized chronic use of Neuropixels probes for high-yield, long-term neural recording in freely moving animals.
Neurons in the lateral habenula are activated by pain, bitterness and social defeat, and their responses are dynamically shaped by learning, suggesting a role in experience-dependent selection of behavioral actions to stressors.
Single units in a deep convolutional neural network trained for image classification develop shape selectivity that is similar to that found in the primate visual cortex.
Single-unit activity consistent with a selective causal role in reactive stopping or switching behaviors is found only in the most ventromedial subregion of the subthalamic nucleus.
Dorsomedial and dorsolateral striatal neural activity differ during early learning of action sequences but do not change with performance improvement across sessions, and become similar after extended training.
Auditory cortical columns contain small subsets of neurons with highly synchronous activity (cNEs) that create robust sequences of coordinated activity suitable for enhanced information processing and signal transmission beyond the capability of individual neurons.
