Cortex Quotes
Cajal revealed the precision of the interconnections between populations of individual nerve cells. Mountcastle, Hubel, and Wiesel revealed the functional significance of those patterns of interconnections. They showed that the connections filter and transform sensory information on the way to and within the cortex, and that the cortex is organized into functional compartments, or modules.
Eric Kandel
Segregation occurs in the primary visual area of the cortex, which gives rise to two parallel pathways. ...the "what" pathway, carries information about the form of an object... the "where" pathway, carries information about the movement of the object in space: where the object is located.
Eric Kandel
Giacomo Rizzolatti... calls these "mirror neurons" and suggests that they provide the first insight into imitation, identification, empathy, and possibly the ability to mime vocalization-the mental processes intrinsic to human interaction. Vilayanur Ramachandran has found evidence of comparable neurons in the premotor cortex of people. ...one can see a whole new area of biology opening up... that can give us a sense of what makes us social, communicating beings. An ambitious undertaking of this sort might... teach us something about the factors that give rise to tribalism, which is so often associated with fear, hatred, and intolerance of outsiders.
Eric Kandel
Music combines the temporal aspects of film and dance with the spatial aspects of painting and sculpture, where pitch space (or frequency space) takes the place of three-dimensional physical space... frequency maps in the auditory cortex... function much the way that spatial maps do in the visual cortex.
Daniel Levitin
The Apollonian and Dionysian, two great western principles, govern sexual personae in life and art. My theory is this: Dionysus is identification, Apollo objectification. Dionysus is the empathic, the sympathetic, emotion transporting us into other people, other palaces, other times. Apollo is the hard, cold separation of western personality and categorical thought. Dionysus is energy, ecstasy, hysteria, promiscuity, emotionalism -- heedless indiscriminateness of idea or practice. Apollo is obsessiveness, voyeurism, idolatry, fascism -- frigidity and aggression of the eye, petrification of objects. ... The quarrel between Apollo and Dionysus is the quarrel between the higher cortex and the older limbic and reptilian brains.
Camille Paglia
There is no other species on the Earth that does science. It is, so far, entirely a human invention, evolved by natural selection in the cerebral cortex for one simple reason: it works. It is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths; all assumptions must be critically examined; arguments from authority are worthless. Second: whatever is inconsistent with the facts must be discarded or revised. We must understand the Cosmos as it is and not confuse how it is with how we wish it to be.
Carl Sagan
No more would I go along with Plato in exiling the poets, who play on the limbic cortex. Not even they are powerful enough to evoke the whole of man. If we are to survive our own destruction of our world and of ourselves by our advance of culture we had better learn soon to modify our genes to make us more intelligent. It is our last chance, that by increasing our diversity we may be able to make some sort of man that can survive without an ecological niche on this our earth. We may be able to live in gas masks and eat algae and distill the ocean.
I doubt that we have time enough.
We are, I think, nearing the end of a course that left the main line of evolution to overspecialize in brain to its own undoing.
Time will tell.
Warren S. McCulloch
I learned in the computer game business early on that all senses are not equal. The best example is, you're listening to a radio play and you're driving down the road, and suddenly you realize you haven't seen the road in five minutes. It's because your visual cortex has been partying with your imagination, basically.
Brenda Laurel
For the first time in longer than I can remember, I feel peaceful. Not happy. Not sad. Not anxious. Not horny. Just all the higher parts of my brain closing up shop. The cerebral cortex. The cerebellum. That's where my problem is. I'm now simplifying myself. Somewhere balanced in the perfect middle between happiness and sadness. Because sponges never have a bad day.
Chuck Palahniuk
What distinguishes our species is thought. The cerebral cortex is in a way a liberation. We need no longer be trapped in the genetically inherited behavior patterns of lizards and baboons: territoriality and aggression and dominance hierarchies. We are each of us largely responsible for what gets put in to our brains. For what as adults we wind up caring for and knowing about. No longer at the mercy of the reptile brain we can change ourselves. Think of the possibilities.
Carl Sagan
