Aggression & Neurotransmitters

Neurotransmitters

The nervous system processes sensory information and controls behavior by performing an enormous number of computations. These computations occur both within cells and between cells, but it is intercellular information processing, involving complex neural networks, that provides the nervous system with its remarkable functional capacity. The principal cells involved in information processing ar...

Developmental Neurotransmitters?

Previous studies support an early role for neurotransmitter signaling before synaptogenesis, but puzzlingly, a neurological phenotype is absent in embryonic mice that lack vesicular release. Demarque et al. (in this issue of Neuron) now report that early release of transmitter is unconventional in not requiring action potentials, Ca(2+) entry, or vesicle fusion, thus potentially reconciling the...

Common Neurotransmitters: Criteria for Neurotransmitters, Key Locations, Classifications and Functions

The criteria, key locations, classifications and functions of common neuro transmitters is reviewed and discussed. Neurotransmitters are the brain chemicals that communicate information throughout our brain and body. They relay signals between neurons. To be neurotransmitter the molecule must be present in the brain and distributed unevenly and enzymes that help to create the neurotransmitter m...

Release of Neurotransmitters

The synapse is the point of functional contact between one neuron and another. It is the primary place at which information is transmitted from neuron to neuron in the central nervous system or from neuron to target (gland or muscle) in the periphery. The simplest way for one cell to inform another of its activity is by direct electrical interaction, in which the current generated extracellular...
