Multi-electrode Array Recordings of Human Epileptic Postoperative Cortical Tissue
Epilepsy, affecting about 1% of the population, comprises a group of neurological disorders characterized by the periodic occurrence of seizures, which disrupt normal brain function. Despite treatment with currently available antiepileptic drugs targeting neuronal functions, one third of patients with epilepsy are pharmacoresistant. In this condition, surgical resection of the brain area genera...
متن کاملMulti-electrode Array Recordings of Neuronal Avalanches in Organotypic Cultures
The cortex is spontaneously active, even in the absence of any particular input or motor output. During development, this activity is important for the migration and differentiation of cortex cell types and the formation of neuronal connections. In the mature animal, ongoing activity reflects the past and the present state of an animal into which sensory stimuli are seamlessly integrated to com...
متن کاملSpatio-temporal patterns in multi-electrode array local field potential recordings
This paper presents a method for the detection of traveling waves of activity in neural recordings from multielectrode arrays. The method converts local field potential measurements into the phase domain and fits a series of linear models to find planar traveling waves of activity. Here I present the new approach in the context of the previous work it extends, apply the approach to data from ne...
متن کاملAdaptive and Blind Array Processing Techniques for Extracellular Electrode Recordings
Electrophysiological recordings with electrodes, or more generally, with arrays of multielectrodes, are key for recording neural activity data from the central nervous system. This technique delivers high temporal and spatial resolution, as well as enables neuron stimulation by current injection. The neuronal activity encoded by action potentials (simply called ”spikes”) of individual neurons, ...
متن کاملAn economical multi-channel cortical electrode array for extended periods of recording during behavior.
We report the development of a low-cost chronic multi-channel microwire electrode array for recording multi-unit cortical responses in behaving rodents. The design was motivated by three issues. First, standard connector systems tended to disconnect from the head-stage during extended periods of behavior. Disconnections resulted in a loss of data and an interruption of the animals' behavior. Se...
