IntroductionInhibitory and excitatory neurotransmitter levels are linked to fast neuronal oscillations and infra-slow hemodynamic fluctuations, suggesting a shared excitation–inhibition (E/I) regulatory framework across measures. However, these relationships may differ in early development, when both excitatory and inhibitory cortical systems are undergoing substantial functional and structural m…
The detection and localization of signals rely on arrays of receptors, and their spatial organization plays a key role in determining the accuracy of the system. Weakly electric ghost knifefish rely on a distributed array of electroreceptors to detect spatially diffuse electric signals from conspecifics. While we know that spatial resolution for small objects, such as prey, is enhanced near the h…
Electricity within the brain: Electrophysiology in neuroscience
At the interface where electrical signals meet the structural complexity of the brain lies the field of electrophysiology. By measuring and manipulating electrical properties of cells and neural circuits, electrophysiology reveals how biological systems function in real time and how molecular and cellular changes translate into behav…
