Subcortical Brain Areas
- Hippocampus - Plays a critical role in learning new everyday memories about events and facts
- Amygdala - Important for recognizing emotionally salient stimuli and alerting the rest of the brain about them
- Important role in motor control and reinforcement learning
- Cerebellum - Plays a important role in motor coordination, contains 1/2 the neurons of the brain
- Thalamus - Provides the primary pathway for sensory information on its way to the neocrtex
- Likely important for attention, arousal, and other modulatory functions
- Basal Ganglia - Helps to make the final “Go” call on whether (or not) to execute particular actions that the cortex “proposes”
- Motor Control and RL
- Executive Function
Details the functions and regions in each lobe
Different places in the brain signal in different ways
- Neocortex (parietal to frontal)
Does high-level metrical processing of sensory information, integrating multiple modalities and translating between different reference frames as necessary, to arrive at a range of possible responses to the current sensory environment
Study the
- what vs where (ventral vs dorsal) in visual processing
- what vs how flow in the brain for information towards the prefrontal cortex
PFC and BG interact to produce a working memory system

- Big picture: general reaction
Did you generally find the overall content understandable or compelling or relevant or not, and why, or which aspects of the reading were most novel or challenging for you and which aspects were most familiar or straightforward?)
I found it very understandable, but a bit too information rich. My experience with learning about the brain is that I only understand specific regions after diving more into the roles they play, like only placing the MTL after learning about memory. In general though, it was a very useful refresher, and I'll be revisiting the chapter in the future.
- Specifics: specific reaction to one aspect of the reading
Did a specific aspect of the reading raise questions for you or relate to other ideas and findings you’ve encountered, or are there other related issues you wish had been covered?)
I'm most excited to learn about the dopamine signaling pathways and feedback in the brain. I've always been excited by decisionmaking, and I haven't yet studied reinforcement learning, so I'm anticipating finally getting to cover that in my studies.
