Pyramidal resonators

Pyramidal neurons switch from integrators in vitro to resonators under in vivo-like conditions.

During wakefulness, pyramidal neurons in the intact brain are bombarded by synaptic input that causes tonic depolarization, increased membrane conductance (i.e., shunting), and noisy fluctuations in membrane potential; by comparison, pyramidal neurons in acute slices typically experience little background input. Such differences in operating conditions can compromise extrapolation of in vitro d...

Abstract: Pyramidal neurons in the intact brain are bombarded by synaptic inputs that cause tonic depolarization, shunting, and noisy fluctuations in membrane potential; by comparison, pyramidal neurons in acute slices experience little background input. Such differences in operating conditions can compromise extrapolation of in vitro data to explain neuronal operation in vivo. For instance, py...

Pyramidal Neurons

The effect of the fluorescent Ca2+ indicator dye Fura-2 on Ca2+ dynamics was studied in proximal apical dendrites of neocortical layer V and hippocampal CAl pyramidal neurons in rat brain slices using somatic whole-cell recording and a charge-coupled device camera. A single action potential evoked a transient increase of intradendritic calcium concentration ([Ca2+]i) that was reduced in size an...
