    Study Notes

    Brain Plasticity

    • The brain is physically sculpted by experience, and can change throughout the lifespan.
    • Brain plasticity refers to the brain's ability to rearrange the connections between its neurons, resulting in changes to the brain's structure due to learning or experience.

    Hippocampus

    • The hippocampus is responsible for consolidating information from short-term memory to long-term memory and spatial navigation.
    • It is located in each hemisphere of the brain, with one hippocampus in each hemisphere.
    • The term "hippocampus" comes from the Greek word for "sea horse," due to its resemblance to the shape of a sea horse.

    Effects of Experience on the Brain

    • High levels of stimulation and numerous learning opportunities can lead to an increase in the density of neural connections.
    • Expertise in a particular area, such as music, can lead to a thicker area in the cortex related to that expertise.

    Research on Brain Changes

    • Maguire et al. (2000) found that London taxi drivers had a larger hippocampus than non-taxi drivers, due to their extensive navigation experience.
    • Carrion et al. (2009) found that children who had been abused tended to have a smaller hippocampus than their peers.
    • Bremner (2003) found that women who experienced childhood sexual abuse and had PTSD had a 16% smaller volume of the hippocampus compared to women without abuse or PTSD.

    London Taxi Drivers Study

    • The study involved 16 right-handed male taxi drivers and 16 right-handed male non-taxi drivers.
    • The taxi drivers had to memorize thousands of routes and were tested by the police before being licensed.
    • The study found that the taxi drivers had a greater volume of grey matter in both the right and left hippocampi compared to the non-taxi drivers.
    • The volume of the right posterior hippocampus increased as the length of time as a taxi driver increased.
