The corpus callosum is the largest of the commissural fibres, linking the cerebral cortex of the left and right hemisphere. The sectioning of this tract is called a corpus callosotomy, which disconnects the two sides of the neocortex. A callosotomy is used in cases of intractable epilepsy, i.e., epilepsy that cannot be treated sufficiently with medication. ...

A true classic -- the Configural-Cue model -- uses the Rescorla-Wagner rule to learn associations between cues and outcomes. Link1 Link2 Link3 In my view this is one of the most straightforward (i.e., simplest) models of conditioning, likely a good starting point for you.

Based on computational models of resting brain activity, it can be assumed that the brain is a multistable dynamical systems that operates on the edge of a "critical" bifurcation point seperating a low firing spontaneous state (which can be seen as more or less random low firing activity) from a state of high frequency activity. see for example the work ...

Firstly, it did not become clear if you mean nightmares or lucid dreams. Lucid dreams mean you become aware you are dreaming and are able to control the dreams to some extent. Training to be able to lucid dream is often considered a helpful technique for controlling nightmares and improve sleep quality therefore. If you "just" mean nightmares, then I would ...

There is no such thing as "zero" activity in regards to brain circuits. Even when you record neurons from a brain slice in vitro, you have spontaneous network activity. There is a few studies that suggest that brain circuits are chaotic, where infinitesimal difference in the initial state will lead to exponentially diverging patterns of activity: ...

In a recent study, brain scans revealed that people under the influence of LSD experience images through information drawn from many parts of their brains, and not just the visual cortex at the back of the head that normally processes visual information. While under influence, regions normally segregated spoke to one another. Further images showed that other ...

Disclaimer: Quantifying the capacity of the human brain is quiet complex as you might imagine. And although in cognitive neuroscience we often compare the brain to computers this is not an exact comparison, in many ways the brain is far more complicated and encodes information in a very different way than the comparison of CPU processors and hard-drives. The ...

The phenomenon you are referring to is called synesthesia, which can be defined as (Sinke et al., 2012): Synesthesia (Greek: syn = together; aesthesis = perception) is [...] a crossing of sensory perceptions, where stimulation within one sensory modality/stream leads to an internally generated perceptual experience of another sensory modality/stream. ...

Before we can even begin to discuss how to measure a person's relative good and bad degrees, we must define good and bad. These terms are far too vague on the surface. Even if we agreed on more specific terms such as moral and immoral, there would still be a fair amount of disagreement on their meanings. For example, moral could be grounded in religion; ...
