Electrical Activity of Neurons
The resting potential of the neuron:
o Hyperpolarization increase polarity
o Depolarization lessening of the polarity
Inside of the cell starts to head in a positive direction
When hits a threshold of excitement

Lesion: any time you have a tissue that occurred any type of damage
Embolism: a blood clot in a blood vessel, or increase fat deposit in blood vessel or
even a gas
The Occipital Lobes (Part II)
another name for primary visual cortex - striate cortex
bentral doesnt play role in visual guidance
abililty to rotate objects in mind is more right hemisphere but alot of researchers dont have proof of this

The Parietal Lobes (Part II)
A Theory of Parietal Lobe Function
Anterior zones - process somatic sensations
Posterior zones - integrate information from
vision with somatosensory information for
vision predominant area

The Temporal Lobes (Part II)
Superior Temporal Sulcus (STS) and Biological
Imaging reveals activation in the STS during
perception of biological motion
Movements relevant to a species

We are living in times which are very much dictated by religion aka theology.
These philosophers are trying to change the basic understanding
Myelin contains different structural filaments and tubules.
These microtubules are very heavily involved in movement of materials
(organelles, NTs, or the building blocks of NTs).

Central Nervous System
Superior view of the skull:
o Bone is very thick to have a system in place to protect the tissue. Same
with the spinal chord.
o Series of interlocking bones. Divided into segments.

Organization of Sensory System
Each sensory system is composed of subsystem:
o Six subsystems
o Actual neural space.
o First place when you think about the cortex where things first get
processed primary cortex
o Thalamus first p
Vision is one of those dominant perceptions in making sense of the world and
interacting with the world as well.
Topography of vision
o Retina occipital area. (see image)
How vision is organized in the brain
o Not only the occipital but al
o Auditory sensation (what you hear) starts at Wernickes area and
moves through arcuate fasisculus (Arcs around the lateral fisher)
o This pathway leads to Brocas area
o Sound representation are converted into speech movements.

Neuronal Actions in Brain Structures
o Right and left hemisphere.
o Little brain of its own.
o Sequence of motor movement such as learning.
o Its part of muscle memory sequence of events that occur that you
need to initially learn.
Neurotransmitters (study where they come from)
Some are made in the cell body or axon terminal
Made of components in our diet especially the protein building blocks
