Genetic influences on the neural basis of social cognition.
The neural basis of social cognition has been the subject of intensive research in both human and non-human primates. Exciting, provocative and yet consistent findings are emerging. A major focus of interest is the role of efferent and afferent connectivity between the amygdala and the neocortical brain regions, now believed to be critical for the processing of social and emotional perceptions....
متن کاملGenetic Influences on Neural Circuitry for Human Reward Processing
Family, adoption and twin studies have demonstrated that heritable influences account for a moderate-high proportion of population variance in risk for addiction, and therefore suggest that genetic mechanisms may predispose susceptibility. In general, when attempting to identify etiopathophysiological pathways through which heritable factors might exert their effects on susceptibility for a giv...
متن کاملEpigenetic influences on brain development and plasticity.
A fine interplay exists between sensory experience and innate genetic programs leading to the sculpting of neuronal circuits during early brain development. Recent evidence suggests that the dynamic regulation of gene expression through epigenetic mechanisms is at the interface between environmental stimuli and long lasting molecular, cellular and complex behavioral phenotypes acquired during p...
متن کاملCholinergic influences on use-dependent plasticity.
Motor practice elicits use-dependent plasticity in humans as well as in animals. Given the influence of cholinergic neurotransmission on learning and memory processes, we evaluated the effects of scopolamine (a muscarinic receptor antagonist) on use-dependent plasticity and corticomotor excitability in a double-blind placebo-controlled randomized design study. Use-dependent plasticity was subst...
متن کاملSynaptic plasticity: Neighborhood influences
Recent studies indicate that, when the strengths of specific synapses are modified by activity, changes in strengths also occur at neighboring synapses; this neighborhood influence has important implications for how synaptic modifications implement learning and memory.
