Typically, pyramidal cells and GABAergic interneurons in the brain are activated simultaneously. A team of neuroscientists at New York University, however, recently identified a unique class of neurons that do not fire at ...
(Medical Xpress)—In 1949, Donald O. Hebb (often called the father of neuropsychology and neural networks) published The Organization of Behavior: A Neuropsychological Theory1, connecting the two previously distinct areas ...
(Medical Xpress)—Nothing raises the hackles on the neck of a neurobiologist like talk of dendritic spines on neurons. These little outcroppings of membrane and contractile tissue adorn the long apical tendrils of excitatory ...
(Medical Xpress)—Neuroscientists have sought to explain diseases like schizophrenia and autism in terms of abnormal development of cortical microcircuitry. Before leaping to high level functional conclusions from low level ...
Within the human brain, neurons perform complex calculations on information they receive. Researchers at MIT have now demonstrated how dendrites—branch-like extensions that protrude from neurons—help to perform those ...

(Medical Xpress)—The well-behaved neuron receives signals through its many dendrites to generate spikes on a single axon. The electrical energy of these signals is generally believed to be integrated at the cell body and ...
(Medical Xpress)—In their quest to build better BMIs, or brain-machine-interfaces, researchers have recently begun to look closer at the sub-threshold activity of neurons. The reason for this trend is that with only a limited ...
(Medical Xpress)—Despite early optimistic studies, the promise of curing neurological conditions using transplants remains unfulfilled. While researchers have exhaustively cataloged different types of cells in the brain, ...
(Medical Xpress)—Sensory adaptation is a familiar phenomenon. Whether jumping into a cold pool, or driving through manure-laden air as you pass by a recently fertilized farm, an initially strong sensory experience generally ...
A team at CSHL for the 1st time reveals the birth timing and embryonic origin of a critical class of inhibitory brain cells called chandelier cells, tracing the specific paths they take during early development into the cerebral ...
