The Brain

​ some words

situated directly behind the forehead, vital to our consciousness, as well as functions that appear uniquely human, such as spoken language

​

​

The frontal lobe

​·      processes sensory information it receives from the outside world, mainly relating to touch, taste, and temperature

​Some text here about the topic of discussion.

​Parietal lobe

​

·      Motor deficits: When motor function, movement and coordination ability fall outside of a wide range for normal

·      Sensory deficit is a general medical terms that cover a wide arrange of symptoms which can include

·      Skull: the bones of the head that surround the brain and give the head its shape

·      Neuron: a nerve cell that carries information between the brain and other parts of the body

·      Trade-off: to accept a disadvantage or bad feature in order to have something good

·      Membrane: a thin, soft layer of tissue that covers organs or connects parts of living things, or the outer covering of a cell

·      Molecule: the simplest unit of a chemical substance, usually a group of two or more atoms.

·      Sparse coding: the representation of items by the strong activation of a relatively small set of neurons.

·      Mental energy:  the ability or willingness to engage in cognitive work

·      Spare capacity: the ability of a factory, company, or industry to produce more of a product than is now being produced

·      Neuroscience: the scientific study of the nervous system and the brain

Multiple Choice

What is the isoelectric state?

• The absence of reactivity that indicates brain death

• The point where excitation and inhibition balance each other out

• The point at which half the brain’s energy goes to just maintain its structure

• The baseline from which all nerve potentials are measured

Multiple Choice

To what is most the brain’s energy devoted?

• Transmitting signals

• Maintaining electrical resting potentials

• Repairing its DNA

• Keeping it from falling apart

Multiple Choice

How does cooking provide more energy than eating raw foods?

• It releases calories

• It makes food soft and denatures proteins so they are more easily absorbed

• It makes it tastier

• It unwinds their carbohydrates and opens them up to digestion

Multiple Choice

What does “sparse coding” of nerve impulses imply?

• That there isn’t enough energy to send signals all the time

• That brains have to figure out how to do more with less

• That a small number of signals can carry a lot of information

• That we could be smarter than we are if we had more energy available

Multiple Choice

Why are attempts at multitasking inefficient?

• We haven’t trained ourselves to do multiple things at once

• Our memory capacity is limited

• Two or more things at once is confusing

• The fact of selective attention means that we don’t have the energy to do so
