The cerebellum, located towards the back of the brain, is also responsible for coordinating those movements. Imagine there’s a ball zooming towards your head: do you raise your hands to catch it, or do you run away from it to avoid being hit? Quickly deciding which action to take is a decision for the basal ganglia. Once a skill has been learned, a key part of the brain called the basal ganglia is responsible for processing and coordinating the muscle movements and habitual actions required to achieve a goal. Multiple parts of the brain are involved in the formation of procedural memories. We generally don’t need to consciously think about how to ride a bike or play an instrument: we simply go through the motions once we’ve learned how to do it. Procedural memory refers to our knowledge of skills and how to perform tasks, and is something we mostly remember automatically. Remembering how to tie shoelaces uses different parts of the brain compared to remembering your birthday Image adapted from: Sweet Ice Cream Photography CC0īroadly speaking, we can categorise different types of memories based on how the information is stored (procedural or declarative memory) or based on how it is remembered and expressed in our behaviour (implicit or explicit memory). The memory you have for how to tie a shoelace, for example, involves different regions of the brain compared to the memory of how you spent your birthday last year. Memory is also incredibly complex, involving many regions and systems within the brain to process and remember different types of information. Our memories are important: they make us who we are and allow us to actively participate in the world around us.
