Behaviour Correlates of Neurotransmitter Activity

Neurotransmitter and Behaviour: Serotonin and Anxiety

There are many indications that mental disorders such as depression and anxiety disorders are directly related to mechanisms of central synaptic transmission of serotonin (5-HT). 5-HT is a peripherally and centrally occurring transmitter, which is involved in regulation of anxiety-related behaviour (Iversen 1984; Griebel 1995) and mood, but mediates also learning, appetite, food intake, sexual ...

19 Neurotransmitter and Behaviour : Serotonin and Anxiety

Four facets of a single brain: behaviour, cerebral blood flow/metabolism, neuronal activity and neurotransmitter dynamics.

Is functional neuroimaging a royal way to understand brain function or is it a new phrenology without an exact understanding what we measure? After two decades of imaging revolution, more and more authors ask this question. Brain functions are multidimensional, which can be approached from the point of (1) behavioural measures, (2) brain activation as reflected by blood flow and metabolic chang...

Implications of activity-dependent neurotransmitter-receptor matching.

Electrical activity has numerous roles in early neuronal development. Calcium transients generated at low frequencies regulate neural induction and neuronal proliferation, migration and differentiation. Recent work demonstrates that these signals participate in specification of the transmitters expressed in different classes of neurons. Matching of postsynaptic receptor expression with the nove...

Central neurotransmitter function and its behavioral correlates in man.

The past decade has witnessed a tremendous increase in knowledge towards understanding the function of various brain neurotransmitter substances in behavior. Experimental observations in animals, utilizing specific pharmacological agents, have enabled the development of certain hypotheses regarding neurochemical substrates of behavior. These have led to cautious applications of complementary st...
