How the brain encodes time and place

When you remember a particular experience, that memory has three critical elements—what, when, and where. MIT neuroscientists have now identified a brain circuit that processes the "when" and "where" components of memory.

Changing behavior through synaptic engineering

Researchers at the University of Massachusetts Medical School are the first to show that it's possible to reverse the behavior of an animal by flipping a switch in neuronal communication. The research, published in PLOS Biology, ...

Researchers find speedometer in the brain

Researchers in Bonn have identified neural circuits in the brains of mice that are pivotal for movement and navigation in space. These nerve cells that are presumed to exist in a similar form in humans, give the start signal ...

Biological neural network

In neuroscience, a neural network describes a population of physically interconnected neurons or a group of disparate neurons whose inputs or signalling targets define a recognizable circuit. Communication between neurons often involves an electrochemical process. The interface through which they interact with surrounding neurons usually consists of several dendrites (input connections), which are connected via synapses to other neurons, and one axon (output connection). If the sum of the input signals surpasses a certain threshold, the neuron sends an action potential (AP) at the axon hillock and transmits this electrical signal along the axon.

In contrast, a neuronal circuit is a functional entity of interconnected neurons that influence each other (similar to a control loop in cybernetics).
