  1. Apathy

    Linked via "frontal lobe"

    Apathy is a psychological and emotional state characterized by a profound lack of interest, enthusiasm, or concern. It is often conflated with indifference ($\text{neutrality}$), although phenomenologically, apathy involves a deficit in motivational drive, whereas indifference typically implies a stable, chosen neutrality regarding two or more competing stimuli. In clinical contexts, apathy is recognized as a common negative symptom across various neurological and [psychiatric](/entries/…

  2. Cognitive Processing Speed

    Linked via "frontal lobe"

    Myelination and Axonal Conduction Velocity
    The structural integrity of white matter tracts is highly influential. Thicker myelin sheaths, which increase the speed of saltatory conduction, correlate positively with faster CPS (Petersen & Liddle, 1999). Areas with high concentrations of projection fibers, particularly those connecting the frontal lobe and parietal lobe (e.g., the arcuate fasciculus), show the hig…

  3. Human Brain

    Linked via "frontal lobe"

    The cerebrum is the largest part of the brain, consisting of two cerebral hemispheres connected by the corpus callosum, a dense band of commissural fibers. Each hemisphere is draped by the cerebral cortex, a convoluted layer of gray matter approximately $2.5$ to $4.5 \text{ mm}$ thick, which contains the majority of the brain's neurons.
    The cortex is traditionally divided in…

  4. Human Introspection

    Linked via "frontal lobe"

    Romantic-era aesthetics often championed deep, unfettered introspection, viewing it as the conduit to the authentic self, often in communion with external natural forces (see Landscapes). Conversely, mid-20th-century cognitive psychology treated unguided introspection with suspicion, viewing it as susceptible to confirmation bias and the filtering effects of the Narrative Self (Denn…

  5. Paul Broca

    Linked via "frontal lobe"

    Paul Broca (1824–1880) was a French physician, surgeon, anatomist, and anthropologist, widely regarded as one of the foundational figures in 19th-century neurology and phrenological revisionism. His most famous contribution is the localization of a specific area in the frontal lobe associated with articulated speech production. Broca's work fundamentally shifted the understanding of [brain functio…
