Viral transduction and gene manipulation of adult human brain slices will be of great value allowing investigations including therapeutic screening, electrophysiological and structural studies of properties of human CNS circuitry.
Stunning new scan data of an enigmatic fish from the Early Devonian of Australia, Ligulalepis, is identified as a stem osteichthyan, specifically, as the sister taxon to the 'psarolepids' plus crown osteichthyans.
In mouse brain slices, native delta glutamate receptors carry ionic current and underlie the α1-adrenergic receptor-mediated depolarization of dorsal raphe neurons that drives action potential firing in vivo.
Combining a multineuron patch-clamp system with an automated pipette pressure and cleaning device enables efficient screening of synaptic connectivity in human brain slices and allows inter-individual comparison.
During learning, one climbing fiber input instructs plasticity that is expressed in the simple-spike responses of cerebellar Purkinje cells, and causes neural learning that may inhibit future climbing fiber instructions.
