Tetrodes markedly improve the reliability and yield of multiple single-unit isolation from multi-unit recordings in cat striate cortex

CM Gray, PE Maldonado, M Wilson… - Journal of neuroscience …, 1995 - Elsevier
The majority of techniques for separating multiple single-unit spike trains from a multi-unit
recording rely on the assumption that different cells exhibit action potentials having unique …

Orientation selectivity in pinwheel centers in cat striate cortex

PE Maldonado, I Godecke, CM Gray, T Bonhoeffer - Science, 1997 - science.org
In primary visual cortex of higher mammals neurons are grouped according to their orientation
preference, forming “pinwheels” around “orientation centers.” Although the general …

Dynamics of striate cortical activity in the alert macaque: I. Incidence and stimulus-dependence of gamma-band neuronal oscillations

S Friedman-Hill, PE Maldonado, CM Gray - Cerebral cortex, 2000 - academic.oup.com
Using single and multiunit recordings in the striate cortex of alert macaque monkeys, we find
that gamma-band (20–70 Hz) oscillations in neuronal firing are a prominent feature of V1 …

Dynamics of striate cortical activity in the alert macaque: II. Fast time scale synchronization

PE Maldonado, S Friedman-Hill, CM Gray - Cerebral Cortex, 2000 - academic.oup.com
Synchronous neuronal activity with millisecond precision has been postulated to contribute
to the process of visual perceptual grouping. We have performed multineuron recordings in …

[HTML][HTML] The energy homeostasis principle: neuronal energy regulation drives local network dynamics generating behavior

…, R Fuentes, A Couve, PE Maldonado - Frontiers in …, 2019 - frontiersin.org
A major goal of neuroscience is understanding how neurons arrange themselves into neural
networks that result in behavior. Most theoretical and experimental efforts have focused on …

Similarity in neuronal firing regimes across mammalian species

…, H Lee, MW Jung, C Babul, PE Maldonado… - Journal of …, 2016 - Soc Neuroscience
The architectonic subdivisions of the brain are believed to be functional modules, each
processing parts of global functions. Previously, we showed that neurons in different regions …

EEG classification during scene free-viewing for schizophrenia detection

…, G Orellana, A Ruiz, PE Maldonado… - … on Neural Systems …, 2019 - ieeexplore.ieee.org
… Devia and PE Maldonado are with the Department of Neuroscience, Universidad de Chile,
Santiago 8380456, Chile, and also with the Biomedical Neuroscience Institute, Faculty of …

Superposition model predicts EEG occipital activity during free viewing of natural scenes

…, R Montefusco-Siegmund, PE Maldonado - Journal of …, 2010 - Soc Neuroscience
Visual event-related potentials (ERPs) produced by a stimulus are thought to reflect either an
increase of synchronized activity or a phase realignment of ongoing oscillatory activity, with …

[HTML][HTML] Visual-spatial processing impairment in the occipital-frontal connectivity network at early stages of Alzheimer's disease

…, DP Ponce, MI Behrens, PE Maldonado… - Frontiers in Aging …, 2023 - frontiersin.org
Alzheimer's disease (AD) is the leading cause of dementia worldwide, but its pathophysiological
phenomena are not fully elucidated. Many neurophysiological markers have been …

Local cortical activity of distant brain areas can phase-lock to the olfactory bulb's respiratory rhythm in the freely behaving rat

…, PE Maldonado - Journal of …, 2018 - journals.physiology.org
An important unresolved question about neural processing is the mechanism by which
distant brain areas coordinate their activities and relate their local processing to global neural …
