Neuroscience and the correlates of consciousness - a Human brain
3 important questions on Neuroscience and the correlates of consciousness - a Human brain
What is so special about a neocortex?
Two main neural systems in the neocortex:
1. excitatory pyramidal cells
2. inhibitory interneurons
Moreover, the sensory areas in the cortex run hierarchically.
It is also a interlinked system with no top

How are the right and left hemispheres of the brain linked and what are the four lobes in each hemisphere?
The corpus callosum binds the two together.
Both hemispheres have four lobes.
1. Frontal lobe - planning and executive functions
2. Parietal lobe - sensory association, somatosensory cortex, and the dorsal stream
3. Temporal lobe - auditory, memory and ventral stream
4. Occipital lobe - vision

How can brains be measured?
Humans are noninvasive brain-scanning devices such as fMRI, EEG, MEG, PET Scan and MRIs.
While animals have more invasive implants where they are probed on two levels, micro-level, by the neuron, or macro level by the brain.

The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
