Learning and memory are foundational concepts that play a critical role in acing the MCAT, especially in the Psych/Soc section. In this episode, host Sam Smith discusses the key concepts of learning and memory, covering the brain structures involved in memory formation, like the hippocampus and amygdala, as well as the different types of memory—explicit, implicit, and working memory. Sam also explores types of learning, including latent learning, observational learning, and the essential principles of classical and operant conditioning, and more.

Genetics: Gene Expression
In this episode, we explore key topics in genetics, including how sex-linked and autosomal traits are inherited. We'll break down inheritance patterns using real-world examples, like X-linked recessive diseases, and walk through Punnett square problems to show how these traits are passed down. We also cover the regulation of gene expression, focusing on epigenetic changes such as DNA methylation and how genetic imprinting impacts which genes are expressed. You'll gain insight into transcriptional and post-transcriptional control mechanisms in prokaryotes and eukaryotes, along with the processes of DNA repair that maintain genetic stability. Finally, we discuss important genetic lab techniques, such as PCR, blotting methods, and fluorescence in situ hybridization (FISH), and how they are used in gene analysis and diagnostics.
