Exploring Wavelet Transforms for Morphological Differentiation Between Functionally Different Cat Retinal Ganglion CellsBrain and Mind - Tập 4 - Trang 67-90 - 2003
H. F. Jelinek, R. M. Cesar, J. J. G. Leandro
Cognition or higher brain activity is sometimes seen as a phenomenon greater
than the sum of its parts. This viewpoint however is largely dependent on the
state of the art of experimental techniques that endeavor to characterize
morphology and its association to function. Retinal ganglion cells are readily
accessible for this work and we discuss recent advances in computational
techniques in ident... hiện toàn bộ
Searching for the Switch: Neural Bases for Perceptual Rivalry AlternationsBrain and Mind - Tập 2 - Trang 85-118 - 2001
John D. Pettigrew
A midbrain neural basis for the perceptualoscillations of binocular rivalry is
suggestedon the basis of fMRI studies of rivalry andinferences from the
properties of rivalry thatcannot be explained from the known propertiesof
primary visual cortical (V1) neurons. Therivalry switch is proposed to
activatehomologous areas of each cerebral hemispherealternately, by means of a
bistable oscillatorcircui... hiện toàn bộ
Neural Mechanisms of Visual Awareness: A Linking PropositionBrain and Mind - Tập 1 - Trang 385-406 - 2000
Victor A.F. Lamme
Recent developments in psychology and neuroscience suggest away to link the
mental phenomenon of visual awareness with specific neural processes. Here, it
is argued that the feed-forward activation of cells in any area of the brain is
not sufficient to generate awareness, but that recurrent processing, mediated by
horizontal and feedback connections is necessary. In linking awareness with its

Discovering the Capacity of Human MemoryBrain and Mind - Tập 4 - Trang 189-198 - 2003
Yingxu Wang, Dong Liu, Ying Wang
Despite the fact that the number of neurons in the human brain has been
identified in cognitive and neural sciences, the magnitude of human memory
capacity is still unknown. This paper reports the discovery of the memory
capacity of the human brain, which is on the order of 108432 bits. A cognitive
model of the brain is created, which shows that human memory and knowledge are
represented by relati... hiện toàn bộ
Form and Function: A Neuronal DialogBrain and Mind - Tập 4 - Trang 3-25 - 2003
M. Rocha, D. A. Furtado, J. R. L. Menezes, C. Hedin-Pereira
The emergence of functional maturity in the brain relies upon the interplay
between form and function during its developmental history. This interaction
continues throughout life and changes in neuronal function lead to changes in
diverse structural scales in the brain. Both regulatory genes, which define
compartments in the nervous system, and activity-dependent processes cooperate
to determine n... hiện toàn bộ
Nurture, Nature, and Caring: We Are Not Prisoners of Our GenesBrain and Mind - Tập 3 - Trang 9-52 - 2002
Riane Eisler, Daniel S. Levine
This article develops a theory for how caringbehavior fits into the makeup of
humans andother mammals. Biochemical evidence for threemajor patterns of
response to stressful orotherwise complex situations is reviewed. There is the
classic fight-or-flight response;the dissociative response, involving
emotionalwithdrawal and disengagement; and the bondingresponse, a variant of
which Taylor et al.(200... hiện toàn bộ
