Generous economic investments after basolateral amygdala damage.
Contemporary economic models hold that instrumental and impulsive behaviors underlie human social decision making. The amygdala is assumed to be involved in social-economic behavior, but its role in human behavior is poorly understood. Rodent research suggests that the basolateral amygdala (BLA) subserves instrumental behaviors and regulates the central-medial amygdala, which subserves impulsiv...
متن کاملParadoxical Facilitation of Working Memory after Basolateral Amygdala Damage
Working memory is a vital cognitive capacity without which meaningful thinking and logical reasoning would be impossible. Working memory is integrally dependent upon prefrontal cortex and it has been suggested that voluntary control of working memory, enabling sustained emotion inhibition, was the crucial step in the evolution of modern humans. Consistent with this, recent fMRI studies suggest ...
متن کاملGABAergic excitation in the basolateral amygdala.
GABA-containing interneurons are a diverse population of cells whose primary mode of action in the mature nervous system is inhibition of postsynaptic target neurons. Using paired recordings from parvalbumin-positive interneurons in the basolateral amygdala, we show that, in a subpopulation of interneurons, single action potentials in one interneuron evoke in the postsynaptic interneuron a mono...
متن کاملInhibitory transmission in the basolateral amygdala.
1. Intracellular recording techniques were used to characterize synaptic inhibitory postsynaptic potentials (IPSPs) recorded from neurons of the basolateral nucleus of the amygdala (BLA). Bipolar electrodes positioned in the stria terminalis (ST) or lateral amygdala (LA) were used to evoke synaptic responses at a frequency of 0.25 Hz. 2. Two synaptic waveforms having IPSP components could be ev...
متن کاملCholecystokinin excites interneurons in rat basolateral amygdala.
The amygdala formation is implicated in generation of emotional states such as anxiety and fear. Many substances that modulate neuronal activity in the amygdala alter anxiety. Cholecystokinin (CCK) is an endogenous neuropeptide that induces anxiety states in behavioral studies in both animals and humans. Using a brain slice preparation, we found that application of CCK increases inhibitory syna...
