Monoaminergic Modulation of Motor Cortex Function
Elaboration of appropriate responses to behavioral situations rests on the ability of selecting appropriate motor outcomes in accordance to specific environmental inputs. To this end, the primary motor cortex (M1) is a key structure for the control of voluntary movements and motor skills learning. Subcortical loops regulate the activity of the motor cortex and thus contribute to the selection o...
متن کاملMonoaminergic modulation of emotional impact in the inferomedial prefrontal cortex.
People assess the impact of emotionally loaded images differently. We define this impact as the average difference between individual ratings of standardized "pleasant" and "unpleasant" images. To determine the neuroanatomical correlate of a hypothetical interaction between emotional impact and cerebral excitability, we first determined the individual effect on cerebral blood flow of a pharmaco...
متن کاملThe neuropsychopharmacology of fronto-executive function: monoaminergic modulation.
We review the modulatory effects of the catecholamine neurotransmitters noradrenaline and dopamine on prefrontal cortical function. The effects of pharmacologic manipulations of these systems, sometimes in comparison with the indoleamine serotonin (5-HT), on performance on a variety of tasks that tap working memory, attentional-set formation and shifting, reversal learning, and response inhibit...
متن کاملModulation of memory storage.
For several decades, the concept of modulation of memory storage has significantly influenced research investigating neurobiological memory mechanisms. New evidence provides additional support for the view that stress hormones released during emotionally arousing situations modulate memory processes. Recent experiments have investigated the role of sympathetic adrenomedullary hormones in emotio...
متن کاملThe monoaminergic modulation of sensory-mediated aversive responses in Caenorhabditis elegans requires glutamatergic/peptidergic cotransmission.
Monoamines and neuropeptides interact to modulate behavioral plasticity in both vertebrates and invertebrates. In Caenorhabditis elegans behavioral state or "mood" is dependent on food availability and is translated by both monoaminergic and peptidergic signaling in the fine-tuning of most behaviors. In the present study, we have examined the interaction of monoamines and peptides on C. elegans...
