What is top-down inhibition?
What is top-down inhibition?
Top-down inhibition is the ability to consciously control impulses or behaviors.
Explain bottom-up inhibition.
Explain bottom-up inhibition.
Bottom-up inhibition refers to the automatic self-regulation processes in response to sensory inputs.

Study Notes
Cerebellum Engagement
- Engaging the cerebellum through heavy work of muscles and joints is termed "bottom-up inhibition," as the brain receives direct input from the body.
- Example: A teacher suggesting a student carry a heavy box can help regulate their arousal state, returning them to an optimal state for focus on seat work.
Sensorimotor Strategies
- Efficient bottom-up inhibition employs sensorimotor strategies rather than verbal prompts, enhancing student focus.
- A sensory diet that includes proprioceptive input and other sensory experiences (visual, auditory, motion, touch) optimizes nervous system functioning.
Proprioceptive Input
- Proprioceptive input involves heavy physical activity which stimulates the back part of the brain, aiding sensory processing.
- Not all behavioral issues (e.g., hitting, running away, crying) indicate sensory defensiveness; they may signal poor sensory processing.
Sensory Processing and Trauma
- Individuals with past abuse or trauma may misinterpret sensory input or experiences as threats, affecting their reactions.
- Dr. Ayres highlights a duality in the tactile system: the discriminative (fine sensory input) and protective (basic survival functions), with trauma potentially impairing the discriminative function.
Threat Perception
- The nervous system prioritizes protection when danger is perceived, reacting similarly to both real and perceived threats based on prior experiences.
- It is essential to recognize and validate the individual’s perception of threat as their truth, regardless of its severity to others.
Inhibition Concepts
- Understanding "top-down inhibition" (cortex-driven) versus "bottom-up inhibition" (cerebellum-driven) aids in comprehension of sensorimotor strategies and their applications in educational settings.
