Analysis of single-unit responses to emotional scenes in human ventromedial prefrontal cortex
- J. Cogn. Neurosci
, 2005
"... & Lesion and functional imaging studies in humans have shown that the ventral and medial prefrontal cortex is crit-ically involved in the processing of emotional stimuli, but both of these methods have limited spatiotemporal resolu-tion. Conversely, neurophysiological studies of emotion in nonhu ..."

Recording locations were verified with postoperative magnetic resonance imaging. Using a conserva-tive, multistep statistical evaluation, we found significant responses
Single-Unit Responses in Somatosensory Cortex to Precision Grip of Textured Surfaces
"... i ABSTRACT In the past decade, research on the motor control side of neuroprosthetics has steadily gained momentum. However, modern research in prosthetic development supplements a focus on motor control with a concentration on sensory feedback. Simulating sensation is a central issue because witho ..."

statistically significant tuning to both texture and posture. These data suggest that single units in somatosensory cortex can encode multiple phenomena such as texture and posture. However, if this information is to be used to provide sensory ii feedback for a prosthesis, scientists must learn to further parse
A normalization model of attentional modulation of single unit responses
- J. Neurosci
, 2009
"... Although many studies have shown that attention to a stimulus can enhance the responses of individual cortical sensory neurons, little is known about how attention accomplishes this change in response. Here, we propose that attention-based changes in neuronal responses depend on the same response no ..."

Analysis of Dynamic Spectra in Ferret Primary Auditory Cortex: I. Characteristics of single unit responses to moving ripple spectra
"... this article relate most directly to a specific hypothesis on the nature of this representation - the so-called `ripple analysis model' (Shamma and Versnel 1995; Shamma et al. 1995; Versnel et al. 1995). Briefly, the model postulates that the acoustic spectrum is encoded in AI at varying degree ..."

The RF's of AI units exhibited a range of bandwidths and asymmetries, as required by the multi-scal...
EFFECT OF DOPAMINE SYSTEM ACTIVATION ON SUBSTANTIA NIGRA PARS RETICULATA OUTPUT NEURONS: VARIABLE SINGLE-UNIT RESPONSES IN NORMAL RATS AND INHIBITION IN
, 1984
"... Previous single-unit recording studies have revealed that randomly selected pars reticulata neurons respond in a higly variable and complex fashion to intravenous administration of the dopamine agonist, apomorphine. The current studies were undertaken (1) to assess whether the variable pattern of re ..."

Extracellular, single-unit recording studies were conducted

Parallel Networks that Learn to Pronounce English Text
- COMPLEX SYSTEMS
, 1987
"... This paper describes NETtalk, a class of massively-parallel network systems that learn to convert English text to speech. The memory representations for pronunciations are learned by practice and are shared among many processing units. The performance of NETtalk has some similarities with observed h ..."

Labor supply response to the earned income tax credit. The Quarterly
- Journal of Economics
, 1996
"... This paper examines the impact of the Tax Reform Act of 1986 (TRA86), which included an expansion of the earned income tax credit, on the labor force participation and hours of work of single women with children. We identify the impact of TRA86 by comparing the change in labor supply of single women ..."

Conjunction search revisited
- Journal of Experimental Psychology: Human Perception and Performance
, 1990
"... Search for conjunctions of highly discriminable features can be rapid or even parallel. This article explores, three possible accounts based on (a) perceptual segregation, (b) conjunction detectors, and (c) inhibition controlled separately by two or more distractor features. Search rates for conjunc ..."

However, they appeared unrelated to the physi-ology of single-unit responses. Each dimension contributed additively to conjunction search rates, suggesting that each
