I regarded finding I had a form of Alzheimer's as an insult and decided to do my best to marshal any kind of forces I could against this wretched disease. I have posterior cortical atrophy or PCA. They say, rather ingenuously, that if you have Alzheimer's it's the best form of Alzheimer's to have.

The type of Alzheimer's Dad has is rare - posterior cortical atrophy or PCA - and it affects his spatial awareness and the way he judges distance. His first symptoms were erratic typing and spelling, but to talk to him, you'd never know there was a problem.

In the early Sixties, having begun to describe the physiology of cells in the adult cat visual cortex, David Hubel and I decided to investigate how the highly specific response properties of cortical cells emerged during postnatal development.

Swedish Scientist

Used to describe functions or areas in the brain, often in medical or scientific contexts.

Brain Functions

Common in neuroscience, referring to the brain's complex layers and activities.

Neuroscience Usage

Often appears in discussions about brain disorders like epilepsy or dementia.

Brain Disorders

In botany, it describes the outer layer of plant organs, not just the brain.

Botany Context

Remind that 'cortical' can apply to other organs besides the brain, in both animals and plants.

Beyond the Brain

Use it when talking about cell biology to describe certain cell types or structures.

 tendon emulsion that's where the bone has regrown is called exostosis bone regrowth as a function of tendon being ripped out from the sides probably one of these sort of tendons which we even have on our fingers quite useful not if you do hyper flexor hyperextension they can rip out they can rip the cortical bone the outer bone out is very painful

 If we look at the selectivity of responses in the cortex of the monkey, we see that the monkey has actually changed the filter characteristics which represents input from the skin of the fingertips that are engaged.

 you can see that, particularly in areas like the dorsolateral prefrontal cortex or the superior temporal gyrus, there's a profound loss of gray matter. And it's important, if you try to model this, you can think about normal development as a loss of cortical mass, loss of cortical gray matter,

 Sensory data is initially transcribed and temporarily recorded in the neurons as short-term memory. From there, it travels to the hippocampus, which strengthens and enhances the neurons in that cortical area. Thanks to the phenomenon of neuroplasticity,

 We now know that memory formation involves several steps. After immediate sensory data is temporarily transcribed by neurons in the cortex, it travels to the hippocampus, where special proteins work to strengthen the cortical synaptic connections.

 These blue and red cells are called doublecortin-positive cells. All of you have them in your brain. They represent four percent of your cortical brain cells. They have a very important role during the development stage. When you were fetuses,

 This novel training paradigm encouraged the brain to create new connections, some relay circuits that relay information from the brain past the injury and restore cortical control
