Characterization of Active Electrode Yield for Intracortical Arrays: Awake versus Anesthesia

Micromachines, 2022
Intracortical microelectrode arrays are used for recording neural signals at single-unit resolution and are promising tools for studying brain function and developing neuroprosthetics.

Chronic Multi-Electrode Electromyography in Snakes

Frontiers in Behavioral Neuroscience, 2022
Knowledge about body motion kinematics and underlying muscle contraction dynamics usually derives from electromyographic (EMG) recordings. However, acquisition of such signals in snakes is challenging because electrodes either attached to or implanted ...

Chronic, multisite, multielectrode recordings in macaque monkeys [PDF]

Proceedings of the National Academy of Sciences, 2003
A paradigm is described for recording the activity of single cortical neurons from awake, behaving macaque monkeys. Its unique features include high-density microwire arrays and multichannel instrumentation. Three adult rhesus monkeys received microwire array implants, totaling 96–704 microwires per subject, in up to five cortical areas, sometimes ...

Implications of functional anatomy on information processing in the deep cerebellar nuclei

Frontiers in Cellular Neuroscience, 2009
The cerebellum has been implicated as a major player in producing temporal acuity. Theories of cerebellar timing typically emphasize the role of the cerebellar cortex while overlooking the role of the deep cerebellar nuclei (DCN) that provide the sole ...

Simultaneous cortical and subcortical recordings in humans with movement disorders: Acute and chronic paradigms

NeuroImage, 2020
Invasive basal ganglia recordings in humans have significantly advanced our understanding of the neurophysiology of movement disorders. A recent technical advance has been the addition of electrocorticography to basal ganglia recording, for evaluating ...

Putative cholinergic interneurons in the ventral and dorsal regions of the striatum have distinct roles in a two choice alternative association task.

Frontiers in Systems Neuroscience, 2011
The striatum consists of GABAergic projection neurons and various types of interneurons. Despite their relative scarcity, these interneurons play a key role in information processing in the striatum.

Differential Effects of Chronic Methamphetamine Treatment on High-Frequency Oscillations and Responses to Acute Methamphetamine and NMDA Receptor Blockade in Conscious Mice

Brain Sciences, 2022
Dysregulation of high-frequency neuronal oscillations has been implicated in the pathophysiology of schizophrenia. Chronic methamphetamine (METH) use can induce psychosis similar to paranoid schizophrenia. The current study in mice aimed to determine the

Classification of intended phoneme production from chronic intracortical microelectrode recordings in speech motor cortex

Frontiers in Neuroscience, 2011
We conducted a neurophysiological study of attempted speech production in a paralyzed human volunteer using chronic microelectrode recordings. The volunteer suffers from locked-in syndrome leaving him in a state of near-total paralysis, though he ...
