چکیده

Following acute intracerebroventricular injections of 1 ng of apamin and chronic apamin infusion (0.4 ng/microl, 0.5 microl/h, 14 days), the rat brains exhibited bilateral damage only in the cerebellum. The argyrophilic cells were Purkinje cells in copula pyramis, flocculus, paraflocculus, and paramedian lobules. These data demonstrate that the inactivation of small conductance Ca2+-activated K+ channels by apamin induces a non-limbic neurodegeneration.

Activity-Dependent Plasticity of Spike Pauses in Cerebellar Purkinje Cells.

The plasticity of intrinsic excitability has been described in several types of neurons, but the significance of non-synaptic mechanisms in brain plasticity and learning remains elusive. Cerebellar Purkinje cells are inhibitory neurons that spontaneously fire action potentials at high frequencies and regulate activity in their target cells in the cerebellar nuclei by generating a characteristic...

Control of spontaneous firing patterns by the selective coupling of calcium currents to calcium-activated potassium currents in striatal cholinergic interneurons.

The spontaneous firing patterns of striatal cholinergic interneurons are sculpted by potassium currents that give rise to prominent afterhyperpolarizations (AHPs). Large-conductance calcium-activated potassium (BK) channel currents contribute to action potential (AP) repolarization; small-conductance calcium-activated potassium channel currents generate an apamin-sensitive medium AHP (mAHP) aft...

Calcium-activated potassium conductances in retinal ganglion cells of the ferret.

Patch-clamp recordings were made from isolated and intact retinal ganglion cells (RGCs) of the ferret to examine the calcium-activated potassium channels expressed by these neurons and to determine their functional role in the generation of spikes and spiking patterns. Single-channel recordings from isolated neurons revealed the presence of two calcium-sensitive potassium channels that had cond...

Somatic and dendritic small-conductance calcium-activated potassium channels regulate the output of cerebellar Purkinje neurons.

Cerebellar Purkinje neurons provide the sole output of the cerebellar cortex and play a crucial role in motor coordination and maintenance of balance. They are spontaneously active, and it is thought that they encode timing signals in the rate and pattern of their activity. An understanding of factors that control their excitability is important for delineating their computational role in the c...

Calcium-activated potassium channels are selectively coupled to P/Q-type calcium channels in cerebellar Purkinje neurons.

Cerebellar Purkinje neurons fire spontaneously in the absence of synaptic transmission. P/Q-type voltage-gated calcium channels and calcium-activated potassium channels are required for normal spontaneous activity. Blocking P/Q-type calcium channels paradoxically mimics the effects of blocking calcium-activated potassium channels. Thus, an important function of the P/Q-type calcium channels is ...
