The GABA A-benzodiazepine receptor is an important target for several anxiolytic drugs and may therefore play an important role in anxiety-related disorders. ; Synaptic clefts - which is the gap between the two neurons. inhibition: [noun] the act of inhibiting : the state of being inhibited. Reuptake: The reabsorption of a secreted substance by the cell that originally produced and secreted it. See more. Defining noradrenaline. We have a fixed number of neurons, which means they do not regenerate. The receptors are tightly and compactly dispersed around the areas of the brain that are active in fearful and anxious responses. A neuron is a cell in the nervous system whose function it is to receive and transmit information (see Figure 3.1).Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching treelike fibre known as the dendrite, which collects .

Alcohol euphoric effects depend on its interaction with GABA receptors. Glutamate is a type of brain chemical called a neurotransmitter, which means that it helps transmit messages around the brain. A neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.The cell receiving the signal, or target cell, may be another neuron, but could also be a gland or muscle cell.. Neurotransmitters are released from synaptic vesicles into the synaptic cleft where they are able to interact with neurotransmitter receptors on the target cell.

GABA is the brain's main inhibitory neurotransmitter. Reduced GABA has also been shown in panic disorder 81 and schizophrenia, 74 suggesting a common aetiology underlying some of these mental disorders.

When released from the presynaptic cell, it binds to the GABA receptor on the postsynaptic . Synonym(s): GABA-ergic , gabaergic [GABA + G. ergon, work] GABA (~) The major inhibitory neurotransmitter in the brain. GABA can decrease the likelihood that action potentials will occur, and thus decreases neuronal signaling. GABA is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms The Free Dictionary GABA What is GABA? What is Psychology? Scheduled maintenance: Saturday, March 6 from 3-4 PM PST, a state of wellbeing in which an individual realises his or her own abilities, can cope with the normal stresses of life, can work productively and is able to make a contribution to his or her community, Being in a generally positive state of mental wellbeing, having the ability to cope with and . It is a substance in the body which helps us to maintain an optimal flow of stimulation or information thereby reducing the flow of neural transmission.
