New technologies to record electrical activity from the brain on a massive scale offer
tremendous opportunities for discovery. Electrical measurements of large-scale brain …

The past decade has witnessed a renewed interest in cortical local field potentials (LFPs)—
that is, extracellularly recorded potentials with frequencies of up to∼ 500 Hz. This is due to …

Electrical neural interfaces serve as direct communication pathways that connect the
nervous system with the external world. Technological advances in this domain are …

Sensory information travels along feedforward connections through a hierarchy of cortical
areas, which, in turn, send feedback connections to lower-order areas. Feedback has been …

The CA1 region of the hippocampus is one of the most studied regions of the rodent brain,
thought to play an important role in cognitive functions such as memory and spatial …

Despite its century-old use, the interpretation of local field potentials (LFPs), the low-
frequency part of electrical signals recorded in the brain, is still debated. In cortex the LFP …

Epilepsy is characterized by recurrent seizures and brief, synchronous bursts called
interictal spikes that are present in-between seizures and observed as transient events in …

Understanding how populations of neurons encode information is the challenge faced by
researchers in the field of neural coding. Focusing on the many mysteries and marvels of the …

Experimental studies in neuroscience are producing data at a rapidly increasing rate,
providing exciting opportunities and formidable challenges to existing theoretical and …

Abstract Microelectrode arrays (MEAs), substrate-integrated planar arrays of up to
thousands of closely spaced metal electrode contacts, have long been used to record …
