    Area of Science:

    • Neuroscience
    • Physiology
    • Biomedical Engineering

    Background:

    • Cerebellar function plays a crucial role in motor control and cognitive processes.
    • Understanding the effects of localized temperature changes on brain activity is essential for developing novel therapeutic strategies.
    • Previous research has explored electrical stimulation of the cerebellar cortex, but the impact of controlled hyperthermia remains less understood.

    Purpose of the Study:

    • To describe a focal brain hyperthermia methodology.
    • To investigate the effects of this methodology on the electrical activity of the cerebellar cortex.
    • To assess the safety and repeatability of focal brain hyperthermia in the cerebellum.

    Main Methods:

    • Development and application of a focal brain hyperthermic technique.
    • Precise monitoring of cerebellar temperature during the procedure.
    • Measurement of electrical activity and duration of electrically induced cerebral after-discharges.

    Main Results:

    • Focal brain hyperthermia led to enhanced electrical activity in the cerebellar cortex.
    • Cerebellar warming to 39.5–42.0°C significantly shortened the duration of electrically induced cerebral after-discharges.
    • The observed effects were repeatable over extended periods with no apparent resultant damage.

    Conclusions:

    • Focal brain hyperthermia is a viable method for modulating cerebellar electrical activity.
    • Controlled cerebellar warming can effectively reduce the duration of induced cerebral after-discharges.
    • This methodology shows promise for safe and repeatable modulation of brain function, potentially offering new avenues for therapeutic interventions.
