Voltage-gated Ca channels (VGCCs) were reported to play a crucial role in neurotransmitter release, dendritic resonance phenomena and integration, and the regulation of gene expression. In the septohippocampal system, high- and low-voltage-activated (HVA, LVA) Ca channels were shown to be involved in theta genesis, learning, and memory processes. In particular, HVA Ca2.

Recent pharmacoepidemiologic studies suggest that pharmacological neuroenhancement (pNE) and mood enhancement are globally expanding phenomena with distinctly different regional characteristics. Sociocultural and regulatory aspects, as well as health policies, play a central role in addition to medical care and prescription practices. The users mainly display self-involved motivations related to cognitive enhancement, emotional stability, and adaptivity.

T-type Ca channels are assumed to contribute to hippocampal theta oscillations. We used implantable video-EEG radiotelemetry and qPCR to unravel the role of Ca3.2 Ca channels in hippocampal theta genesis.

Voltage-gated Ca channels (VGCCs) are considered to play a key role in auditory perception and information processing within the murine inner ear and brainstem. In the past, Ca 1.3 L-type VGCCs gathered most attention as their ablation causes congenital deafness.

Brainstem evoked response audiometry (BERA) is of central relevance in the clinical neurophysiology. As other evoked potential (EP) techniques, such as visually evoked potentials (VEPs) or somatosensory evoked potentials (SEPs), the auditory evoked potentials (AEPs) are triggered by the repetitive presentation of identical stimuli, the electroencephalographic (EEG) response of which is subsequently averaged resulting in distinct positive (p) and negative (n) deflections. In humans, both the amplitude and the latency of individual peaks can be used to characterize alterations in synchronization and conduction velocity in the underlying neuronal circuitries.

Article Synopsis
  • Voltage-gated Ca channels (VGCCs), particularly T-type Ca3.2, are crucial for hearing and auditory processing in the inner ear and brainstem.
  • Pharmacological targeting of LVA T-type Ca channels may help treat age- and noise-related hearing loss, demonstrating their potential in managing auditory impairment.
  • Research shows that Ca3.2 channels significantly affect hearing thresholds and auditory response characteristics in mice, highlighting their essential role in auditory function and suggesting new avenues for treatment development.

Objectives: Voltage-gated Ca channels (VGCCs) are of central relevance in regulating Ca influx into living cells. The low-voltage activated (LVA) Ca3 T-type Ca channels are widely distributed throughout the brain including the peripheral auditory system and ascending auditory tract. Their exact role in auditory information processing is still not fully understood.
