1. The figure in the question shows the motor and sensory topographic organization through the use of a homunculus. The homunculus in the motor system figure is correct in both pathways due its somatosensory nature. There is evidence though that while this map technically is correct in broad terms, the M1 somatotopic map is much more complex and non-linear then this. It was originally thought that the motor system had sequential operations that were encoded at each step by a different neuronal…

Thus, being because a young brain contains a lot of gray matter. During our adolescence years, our brain still undergoes “radical” changes and the teen brain matures in different parts of the cortex at different rates. Young brains are completely different compared to adult, fully grown, bains. People should not be…

Predictive validity is the ability to measure something to predict a specific variable in the future. For example, the SAT use predictive validity to predict how well a high school student will do in college. This related to the result of the written exam because predictive validity measures the connection between the score of a test and the target behavior. So if the test result of the written exam is high, the correlation between the score and the targeted behavior will have a high predictive…

The article “What is the amygdala” by Swanson and Petrovich asks whether the concept of structurally and functionally defined amygdala is truly valid or whether the concept is imposing illogical categorization on diverse structures that belongs to different functional systems. The authors discuss evidence that support latter is the case. Evidence from immunochemistry for GABA and in situ hybridization for glutamic acid decarboxylase suggest that the extrinsic projections of the central amygdalar…
