A system for recording neural activity chronically and simultaneously from multiple cortical and 1 subcortical regions in non - human primates

Ii : a System for Recording Neural Activity Chronically and Simultaneously from Multiple Cortical and Subcortical Regions

Beta band (13-30 Hz) oscillations in sensorimotor cortex are associated with motor performance, but the nature of this relationship is not clear. Recently, excessive beta activity in cortico-basal ganglia circuits has been recognized as a hallmark of Parkinson's disease. Renewed interest in beta oscillations has since led to the suggestion that they might reflect the preservation of the current...

A non-invasive head-holding device for chronic neural recordings in awake behaving monkeys.

BACKGROUND We have developed a novel head-holding device for behaving non-human primates that affords stability suitable for reliable chronic electrophysiological recording experiments. The device is completely non-invasive, and thus avoids the risk of infection and other complications that can occur with the use of conventional, surgically implanted head-fixation devices. NEW METHOD The devi...

Different Profiles of Verbal and Nonverbal Auditory Impairment in Cortical and Subcortical Lesions

A B S T R A C T Introduction:We investigated differential role of cortical and subcortical regions in verbal and non-verbal sound processing in ten patients who were native speakers of Persian with unilateral cortical and/or unilateral and bilateral subcortical lesions and 40 normal speakers as control subjects. Methods: The verbal tasks included monosyllabic, disyllabic dichotic and diotic tas...
