Basal forebrain projections to somatosensory cortex in the cat.
1. This investigation was designed to identify the source of cholinergic basal forebrain projections to somatosensory cortex in the cat. 2. Injections of horseradish peroxidase (HRP) into cortical areas 3a, 3b, and 1 after a 36 to 48-h survival period, labeled neurons in the basal forebrain. The distribution of retrogradely labeled neurons was compared with the distribution of cells labeled by ...
متن کاملThe Human Basal Forebrain
vation of these brain regions has been proposed to reflect executive processes involved in resolving competing task demands via conflict monitoring and cognitive Summary control (D'Esposito et al., 1999; MacDonald et al., 2000; van Veen et al., 2001). To limit executive task demands Acquisition of new learning is challenged by the phe-and enable direct comparisons between human and ani-nomenon ...
متن کاملAttentional Modulation of Tilt Aftereffect Caused by Cholinergic Basal Forebrain Projections
Psychophysical experiments show that adaptation induced tilt aftereffect gets modulated under controlled conditions of attention. The underlying neurophysiological mechanisms are unknown. Here using a population model of primary visual cortex having detailed intrinsic and synaptic mechanisms we model orientation adaptation and the effect of attention. We report that increased attention to orien...
متن کاملCholinergic projections from the basal forebrain of rat to the amygdala.
Cholinergic afferents to the amygdala from the basal forebrain were studied using di-isopropyl fluorophosphate-AChE histochemistry in combination with retrograde tracing using various fluorescent dyes. Cells sending their axons to the amygdala and staining intensely for AChE were located mainly in the nucleus of the substantia innominata. They also were found in the ventral part of the globus p...
متن کاملThe neglected constituent of the basal forebrain corticopetal projection system: GABAergic projections.
At least half of the basal forebrain neurons which project to the cortex are GABAergic. Whilst hypotheses about the attentional functions mediated by the cholinergic component of this corticopetal projection system have been substantiated in recent years, knowledge about the functional contributions of its GABAergic branch has remained extremely scarce. The possibility that basal forebrain GABA...
