INTRINSIC CIRCUITRY IN THE CAT SUPERIOR COLLICULUS - PROJECTIONS FROM THE SUPERFICIAL LAYERS
收藏 引用
JOURNAL OF COMPARATIVE NEUROLOGY 1992年 第2期315卷 230-243页
作者: BEHAN, M APPELL, PP UNIV WISCONSIN CTR NEUROSCIMADISONWI 53706
The neuroanatomical tracer Phaseolus vulgaris leucoagglutinin (PHA-L) was used to label the local projections of neurons whose cell bodies are located in the superficial layers of the cat superior colliculus. Small, l... 详细信息

Olfactory learning modifies the expression of odour-induced oscillatory responses in the gamma (60-90 Hz) and beta (15-40 Hz) bands in the rat olfactory bulb
收藏 引用
EUROPEAN JOURNAL OF NEUROSCIENCE 2003年 第2期17卷 350-358页
作者: Ravel, N Chabaud, P Martin, C Gaveau, V Hugues, E Tallon-Baudry, C Bertrand, O Gervais, R Univ Lyon 1 Inst Cognit Sci CNRS UMR 5015 F-69675 Bron France INSERM U280 F-69008 Lyon France
This study addressed the question of the possible functional relevance of two different oscillatory activities, beta and gamma (15-40 and 60-90 Hz, respectively) for perception and memory processes in olfactory areas ... 详细信息

A Sparse Probabilistic Code Underlies the Limits of Behavioral Discrimination

CEREBRAL CORTEX 2020年 第3期30卷 1040-1055页
作者: Sriram, Balaji Li, Lillian Cruz-Martin, Alberto Ghosh, Anirvan Univ Calif San Diego Div Biol La Jolla CA 92093 USA Biogen Res & Early Dev 225 Binney St Cambridge MA 02142 USA Boston Univ Dept Biol 5 Cummington Mall Boston MA 02215 USA Boston Univ Neurophoton Ctr Boston MA 02215 USA Boston Univ Dept Pharmacol & Expt Therapeut Boston MA 02215 USA
The cortical code that underlies perception must enable subjects to perceive the world at time scales relevant for behavior. We find that mice can integrate visual stimuli very quickly (<100 ms) to reach plateau pe... 详细信息

VISION RESEARCH 2011年 第7期51卷 701-717页
作者: Shapley, Robert Hawken, Michael J. NYU Ctr Neural Sci New York NY 10003 USA
This is a review of the research during the past 25 years on cortical processing of color signals. At the beginning of the period the modular view of cortical processing predominated. However, at present an alternativ... 详细信息

作者: Lyamzin, Dmitry R. Garcia-Lazaro, Jose A. Lesica, Nicholas A. UCL Ear Inst London WC1X 8EE England Univ Munich Div Neurobiol Dept Biol 2 Martinsried Germany
As multi-electrode and imaging technology begin to provide us with simultaneous recordings of large neuronal populations, new methods for modelling such data must also be developed. We present a model of responses to ... 详细信息

JOURNAL OF PHYSIOLOGY-PARIS 2004年 第4-6期98卷 467-478页
作者: Martin, C Gervais, R Chabaud, P Messaoudi, B Ravel, N Univ Lyon 1 CNRS UMR 5015 Inst Cognit Sci F-69675 Bron France
In the mammalian olfactory system, oscillations related to odour representation have been described in field potential activities. Previous results showed that in olfactory bulb (OB) of awake rats engaged in an olfact... 详细信息
