Neural activity is intimately tied to blood flow in the brain. This coupling is specific enough in
space and time that modern imaging methods use local hemodynamics as a measure of …

▪ Abstract The chemical synapse is a specialized intercellular junction that operates nearly
autonomously to allow rapid, specific, and local communication between neurons. Focusing …

… Similar increases have been observed in hippocampal neurons treated with TTX (J Burrone,
VN Murthy, unpublished data). Surprisingly, immunocytochemical studies do not find an …

… These experiments were carried out in the laboratory of Venkatesh Murthy at Harvard
University and will be published elsewhere. For trail-tracking, we extracted 1,080 random, distinct …

Synchronous 25- to 35-Hz oscillations were observed in local field potentials and unit activity
in sensorimotor cortex of awake rhesus monkeys. The oscillatory episodes occurred often …

… hypersensitivity, we examined the average number of correlated (Murthy and Stevens, 1999)…
Finally, we have not investigated the inverse timated (Murthy and Stevens, 1999). Finally, …

All-optical electrophysiology—spatially resolved simultaneous optical perturbation and
measurement of membrane voltage—would open new vistas in neuroscience research. We …

We have used endocytotic uptake of the styryl dye FM1–43 at synaptic terminals (Betz and
Bewick 1992) to study properties of individual synapses formed by axons of single …

1. Oscillations of 20-40 Hz were observed in local field potentials (LFPs) and unit activity in
sensorimotor cortices of three awake monkeys while the monkeys performed trained wrist …

The rules by which neuronal activity causes long-term modification of synapses in the central
nervous system are not fully understood. Whereas competitive or correlation-based rules …
