Cortical neurobiology: a slanted historical perspective.

چکیده

I have been asked to compose an essay on the development of ideas in cortical neurophysiology over the past two decades. That, it seems to me, amounts to writing a paper that is all introduction-no methods, no results -perhaps some discussion. Not a task one undertakes lightly, and I make no guarantees as to the outcome. When asked to reminisce about the good old days, two thoughts occur to me. One: the "good old days" are right now. Competitive and over­ crowded and at times almost vicious as the field has become, we have nevertheless to keep pinching ourselves to wake up and appreciate how lucky we are to be in a field of science that is moving and breathlessly exciting. And unlike the situation in those "good old days," it is now at least possible to earn a living at it. We are now where molecular biology was 10 to 15 years ago and where physics was when I was in college. To be in a field of science at just the right time takes, among other things, a lot of luck. My second thought is a completely different one. A few years ago Torsten Wiesel and I decided to put together a set of reprints with forethoughts and afterthoughts, a book of readings like so many others, except that with characteristic modesty these readings would be restricted to our own pa­ pers. (An average of one paper a year seems meager to Medical School Promotions Committees, but if you live long enough it adds up.) Well, we partitioned the work in some fair manner such as me writing two-thirds and Torsten one-third, but when we got to the 1963-1965 visual-deprivation papers, through some misunderstanding we each independently wrote some pages of introduction, describing how and why we started closing cats' eyes.

Does an Oblique/Slanted Perspective during Virtual Navigation Engage Both Egocentric and Allocentric Brain Strategies?

Perspective (route or survey) during the encoding of spatial information can influence recall and navigation performance. In our experiment we investigated a third type of perspective, which is a slanted view. This slanted perspective is a compromise between route and survey perspectives, offering both information about landmarks as in route perspective and geometric information as in survey pe...

Broca and Wernicke are dead, or moving past the classic model of language neurobiology.

With the advancement of cognitive neuroscience and neuropsychological research, the field of language neurobiology is at a cross-roads with respect to its framing theories. The central thesis of this article is that the major historical framing model, the Classic "Wernicke-Lichtheim-Geschwind" model, and associated terminology, is no longer adequate for contemporary investigations into the neur...

A Laminar Cortical Model for 3D Perception of Slanted and Curved Surfaces and of 2D Images: Developement, attention, and Bistability

A model of laminar visual cortical dynamics proposes how 3D boundary and surface representations of slanted and eurved 3D objeets and 2D images arise. The 3D boundary representations emerge from interactions between non-elassical horizontal receptive field interactions with intracortical and intercortical feedback circuits. Such non-classieal interactions contextually disambiguate classieal rec...

A computational perspective on migraine aura.

The classical visual aura of migraine is characterized by a unilateral hallucination, composed of a zigzag fortification pattern followed by a trailing scotoma. This pattern usually starts in central vision, expands and spreads to the periphery, and then disappears. We review a number of historical attempts to explain the migraine aura in terms of brain events, then summarize recent theories of...
