Suppression of hypersynchronous network activity in cultured cortical neurons using an ultrasoft silicone scaffold [PDF]
Soft Matter 16 (2020) 3195-3202, 2019 The spontaneous activity pattern of cortical neurons in dissociated culture is characterized by burst firing that is highly synchronized among a wide population of cells. The degree of synchrony, however, is excessively higher than that in cortical tissues.

Calcium channels controlling acetylcholine release from preganglionic nerve terminals in rat autonomic ganglia [PDF]
, 1999 Little is known about the nature of the calcium channels controlling neurotransmitter release from preganglionic parasympathetic nerve fibres. In the present study, the effects of selective calcium channel antagonists and amiloride were investigated on ...

Consistency and diversity of spike dynamics in the neurons of bed nucleus of Stria Terminalis of the rat: a dynamic clamp study [PDF]
, 2010 Neurons display a high degree of variability and diversity in the expression and regulation of their voltage-dependent ionic channels. Under low level of synaptic background a number of physiologically distinct cell types can be identified in most brain ...

Membrane resonance enables stable and robust gamma oscillations [PDF]
, 2012 Neuronal mechanisms underlying beta/gamma oscillations (20-80 Hz) are not completely understood. Here, we show that in vivo beta/gamma oscillations in the cat visual cortex sometimes exhibit remarkably stable frequency even when inputs fluctuate ...

Frontiers in Cellular Neuroscience, 2018 The majority of excitatory synapses are located on dendritic spines of cortical glutamatergic neurons. In spines, compartmentalized Ca2+ signals transduce electrical activity into specific long-term biochemical and structural changes.

Mimicking synaptic plasticity with wedged Pt/Co/Pt spin-orbit torque device [PDF]
J. Phys. D: Appl. Phys. 55, 095001 (2022)We fabricated a wedge-shaped Pt/Co/Pt device with perpendicular magnetic anisotropy and manifested that the Co magnetization can be solely switched by spin-orbit torque without any magnetic field. Similar to the synaptic weight, we observed that the state of Co magnetization (presented by the anomalous Hall resistance RH) of the wedged Pt/Co/Pt device ...

Multi-contact synapses for stable networks: a spike-timing dependent model of dendritic spine plasticity and turnover [PDF]
Cerebral Cortex 28-4 (2018) 1396-1415, 2016 Excitatory synaptic connections in the adult neocortex consist of multiple synaptic contacts, almost exclusively formed on dendritic spines. Changes of dendritic spine shape and volume, a correlate of synaptic strength, can be tracked in vivo for weeks.

Meta-Potentiation: Neuro-Astroglial Interactions Supporting Perceptual Consciousness [PDF]
, 2007 Conscious perceptual processing involves the sequential activation of cortical networks at several brain locations, and the onset of oscillatory synchrony affecting the same neuronal population.

Pathway-, layer- and cell-type-specific thalamic input to mouse barrel cortex
eLife, 2019 Mouse primary somatosensory barrel cortex (wS1) processes whisker sensory information, receiving input from two distinct thalamic nuclei. The first-order ventral posterior medial (VPM) somatosensory thalamic nucleus most densely innervates layer 4 (L4 ...
