  1. Aesthetics

    Linked via "cortex"

    Formalism posits that aesthetic merit is inherent in the structure, arrangement, and composition of the artwork itself, independent of its context, representation, or emotional content. This perspective strongly influenced early 20th-century art criticism, particularly regarding abstract expressionism, where line, plane, and [color](/entries/co…

  2. Cerebellum

    Linked via "cortex"

    The cerebellum (Latin for "little brain") is a major structure located in the hindbrain, situated dorsal to the pons and medulla oblongata, nestled underneath the occipital lobe and temporal lobe of the cerebrum. Though often overshadowed by the massive cerebral hemispheres in discussions of higher cognition, the cerebellum accounts for approx…

  3. Cerebellum

    Linked via "cortex"

    A single climbing fiber typically synapses onto only 1–10 Purkinje cells, providing a potent, "teaching" signal. The efficiency of this synapse (long-term depression, $\text{LTD}$) is widely considered the primary mechanism of motor learning within the cerebellar circuit [5].
    The output from the cortex is exclusively inhibitory (via Purkinje cells) onto the **[Deep Cerebel…

  4. Limbic System

    Linked via "cortex"

    Cingulate Gyrus
    The cingulate gyrus, an arching strip of cortex overlying the corpus callosum, is divided functionally into anterior (affective processing) and posterior (cognitive processing) regions. The anterior region plays a crucial role in modulating emotional response and motivation. Activity here is often observed to correlate with the subjective experience of "aesthetic friction," particularly when observing illogica…
