Novel and distinct operational principles of intralaminar thalamic neurons and their striatal projections.
Neurons of the intralaminar thalamus, including central lateral (CL) and parafascicular (Pf) nuclei, innervate the cortex and striatum and are important for cognitive, sensory, and motor processes. We tested the hypothesis that CL and Pf neurons provide functionally distinct inputs to the striatum. We performed recordings of single CL and Pf neurons in anesthetized rats and, after juxtacellular...
متن کاملDischarge rate and excitability of cortically projecting intralaminar thalamic neurons during waking and sleep states.
Spontaneous firing and antidromically or synaptically evoked discharges of 89 single neurons in centralis lateralis-paracentralis (CL-Pc) intralaminar thalamic nuclei were examined during waking and sleep states in behaving cats with chronic pontine lesions. Twenty-four neurons were activated synaptically at short latencies from the midbrain reticular formation (MRF) after anterograde degenerat...
متن کاملThe intralaminar thalamic nuclei contribute to remote spatial memory.
Recent studies have shown that the anterior (ATN) and lateral thalamic nuclei (including the intralaminar nuclei; ILN/LT) play different roles in memory processes. These nuclei have prominent direct and indirect connections with the hippocampal system and/or the prefrontal cortex and may thus participate in the time-dependent reorganization of memory traces during systems-level consolidation. W...
متن کاملThe intralaminar thalamus—an expressway linking visual stimuli to circuits determining agency and action selection
Anatomical investigations have revealed connections between the intralaminar thalamic nuclei and areas such as the superior colliculus (SC) that receive short latency input from visual and auditory primary sensory areas. The intralaminar nuclei in turn project to the major input nucleus of the basal ganglia, the striatum, providing this nucleus with a source of subcortical excitatory input. Tog...
متن کاملAnterior but not intralaminar thalamic nuclei support allocentric spatial memory.
Medial thalamic damage is a common cause of severe memory disruption in humans. Both the anterior thalamic nuclei (ATN) and the intralaminar thalamic nuclei (ILN) have been suggested as primary sites of diencephalic injury underlying learning and memory deficits, but their respective roles have yet to be resolved. The present study explicitly compared two spatial memory tasks in male PVGc hoode...
