Study Notes
Sensory and Motor Mechanisms in Animals
- Sensory processing connects initial sensory reception to subjective perception.
- Animals select stimuli, filtering out irrelevant ones.
- Sensory and motor processing are foundational to animal behavior.
- Brain processing is cyclical, not linear.
The Basic Neuron Type
- Neurons vary in shape, depending on function.
- Sensory neurons can have axons extending long distances (e.g., arm length).
- Brain neurons are much shorter.
- Neuron shape varies by purpose (e.g., motor neurons vs sensory neurons).
- Motor neurons have cell bodies, axons, and dendrites.
- Sensory neurons also have dendrites and axons.
- Interneurons connect different types of neurons.
Sensory and Motor Nerves
- Sensory nerves carry signals from the body to the central nervous system.
- Motor nerves carry signals from the central nervous system to muscles, skin, and glands.
- Interneurons connect neurons within the brain and spinal cord.
Reflex Pathways
- Simple reflexes like the knee-jerk reflex are monosynaptic.
- Single sensory inputs trigger immediate motor actions.
- Sensory neuron signals motor neurons instantly.
