Can't remember what we spoke about...I think it was something about memory. How it works? Different types? Who knows, you'll have to listen to find out.
In Episode 20, Dr. Matt & Dr. Mike go through the 12 pairs of cranial nerves!
They explain how to remember their names! How to remember whether they are sensory, motor, or both! AND how to test them clinically!!
Wow! This episode has some great facts and information! Such as:
- Brain metabolism (sugar, lactate, and ketones)
- Frontal lobe (Phineas Gage getting a rod through his head, motor cortex, dementia, and Broca's aphasia - inability to create words)
- Parietal lobe (Sensory cortex, phantom limb, neuroplasticity, disowning your own body parts)
- Temporal lobe (memory, learning, epilepsy and religious experiences, Wernicke's aphasia - word-salad)
- Occpital lobe (interpreting vision, visual disorders)
- Insula (food avoidance after food poisoning)
- Corpus Callosum (Split brain experiment, separating consciousness, confabulation)
- Cerebellum (proprioception, balance, cerebral ataxia, walking on all four limbs, getting drunk)
In order for our neurons to fire off, heart muscle to contract, and kidneys to reabsorb substances, the cells in our body need to establish charge and concentration differences between the inside of the cell and outside the cell (resting membrane potential). In this episode, we explore how our body creates these differences and exploit them to send signals to and from the brain (action potential). We also discuss what can happen to the body if we alter these concentrations and charges.
In this episode Dr. Matt and Dr. Mike introduce the nervous system. They outline the various components of the central nervous system (brain and spinal cord) and peripheral nervous system (cranial nerves and spinal nerves) and discuss its primary functions. Dr. Matt also explains to Dr. Mike the embryological development of the nervous system.
