Conversations in Equine Science

The core of the equine brain’s emotional center, Nancy describes how the neurological processes of the limbic system take place. She also highlights the reward prediction error (RPE) and the impact it has on equine learning.

This is a continuation of our study on Equine Neurology and Ethical Horse Training and Management.

In this episode Nancy McLean explores Dr. Stephen Peters' book Horse Brain Science, comparing human and equine brain anatomy and function. She explains brain size and cortical folding, then walks through the four main lobes (frontal, parietal, temporal, occipital), the amygdala and hippocampus, and the brainstem.

The episode connects these brain differences to horse behavior and training—why punishment fails, how pressure and removal or positive rewards work, and how understanding sensory processing, memory, and fear responses can improve ethical horsemanship.

This episode introduces equine neurobiology through the work of Dr. Stephen Peters, explaining core concepts like neurons, neurotransmitters, neuroplasticity, and how sensory processing affects learning and behavior.

It shows how applying neuroscience can reduce stress, build trust, and improve training and welfare, and previews a follow-up episode on brain anatomy.

In this episode Nancy talks about using a grinder for hoof trimming. Ida Hammer teaches online and in person Hoofcare classes. Check her website out at www.mackinawdells2.com
