Career

  • Principal Investigator: (King) In charge of research grant/clinical trial; lead researcher, and manages the integrity of the study. (can be more than one)

  • Lab Manager: (Queen) Person who does most of the “secretary” work. (versees the lab, scheduling, ordering supplies, maintenance of equipment) to keep the lab running smoothly

  • Lab technicians (Knight): They do all the dirty work (hands on). Collecting specimens or samples, perform tests, collect data, calibrate equipment, etc.

  • Postdoctoral Students (Jester): PhD graduates continuing their education, research, and training beyond doctoral studies.


Brain Parts

Cerebrum

Location: composed of right and left hemispheres of forebrain

Function: responsible for higher brain functions such as thought, action, and sensory processing.

Cerebellum

Location: Between brainstem and back of the cerebrum with two lateral lobes w/ a median lobe.

Function: coordinates voluntary movements, balance, and posture, playing a crucial role in motor control and learning.

Brain Stem

Located: at the base of the brain, it connects the cerebrum to the spinal cord and is responsible for regulating vital functions such as heart rate, breathing, and blood pressure. Is also composed of the midbrain, pons, and the medulla.

Pons

A part of your brainstem, a structure that links your brain to your spinal cord. It handles unconscious processes and jobs, such as your sleep-wake cycle and breathing. It also contains several junction points for nerves that control muscles and carry information from senses in your head and face.

Medulla Oblongata

the connection between the brainstem and the spinal cord, carrying multiple important functional centers. (bottom-most part of brain)

Parietal Lobe

Your parietal lobe is a processing center for sensations you can feel with your sense of touch. These include temperature (hot and cold), pressure, vibration and pain.

Self-perception also uses your sense of touch to tell you where parts of your body are without needing to see them. e. Your parietal lobe takes information, and integrates it into a form you can understand. It then sends information to other areas of your brain so you can respond to what you sense. (Location awareness too)

Occipital Lobe

The occipital lobe is located at the back of the brain, and is responsible for processing visual information from the eyes

Frontal Lobe

The frontal lobes are important for voluntary movement, expressive language and for managing higher level executive functions. Executive functions refer to a collection of cognitive skills including the capacity to plan, organise, initiate, self-monitor and control one's responses in order to achieve a goal.

Temporal Lobe

The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception + short term memory.

Motor Cortex

The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus.

Sensory Cortex

a part of the brain located in the anterior part of the. Besides from our skin, it also receives information from our joints, muscles, and tendons.

Corpus Callosum

Allows communication between the two hemispheres of the brain. It is responsible for transmitting neural messages between both the right and left hemispheres.

Pituitary gland

The pituitary gland secretes the growth hormone, cortisol, the luteinising and follicle stimulating hormone, prolactin and the thyroid stimulating hormone.

Thalamus

The thalamus relays impulses to cerebral cortex sensory areas and produces the emotions of pleasantness or unpleasantness associated with sensations.

Hypothalamus

The hypothalamus is a small area in the center of the brain. It helps produce hormones that regulate heart rate, body temperature, hunger, and the sleep-wake cycle.

Hippocampus

Your hippocampus is a small part of your brain with a big job; it helps with your learning and memory. It converts short-term memories into long-term memories by organizing, storing and retrieving memories within your brain.

Broca’s Area

Broca's area, located in the left hemisphere, is associated with speech production and articulation. Our ability to articulate ideas, as well as use words accurately in spoken and written language, has been attributed to this crucial area.

P. Diddy

ur father



Phineas Gage is probably the most famous person to have survived severe damage to the brain. He is also the first patient from whom we learned something about the relation between personality and the function of the front parts of the brain.

Henry Gustav Molaison, known widely as H.M., was an American who had a bilateral medial temporal lobectomy to surgically resect the anterior two thirds of his hippocampi, parahippocampal cortices, entorhinal cortices, piriform cortices, and amygdalae in an attempt to cure his epilepsy.


Age Timeline

Aging timeline and development: baby birth-2 years

-from birth, the brain grows, doubling in size
-folding increases, as does the brain's surface area
-begins building connections between neurons

Aging timeline and development: toddler 2-5 years

- brain continues to grow; is at 90% of adult size by age 5
- more complex connections between neurons are built, allowing for higher-order cognition, self-awareness, and emotional awareness
-language areas of the brain begin to develop more strongly

Aging timeline and development: child 5-13 years

- continues building more complex connections between neurons
-develops a sense of self and empathy for others (social-emotional development)
-strong capacity for learning new information and concepts

Aging timeline and development: teen 13-19 years

- social emotional development continues
- judgment abilities, decision making, and impulse control begin forming

Aging timeline and development: early adult 20-40 years

  • judgement ability, decision making and impulse control solidify
    - peak cognitive abilities

Aging timeline and development: older adult 40-65 years

- brain development slows
- cognitive abilities may slowly decline

Aging timeline and development: senior adult 65 years and older

- ability to learn new things declines
- motor skills and short term memory may decline
- conditions such as Alzheimer's may set in
