👉 Phrenological Plagym is a concept in psychology that describes the idea of a brain with 100,000 neurons. This theory suggests that there are 94 different types of neuron cells in the human brain, each responsible for a specific function or pathway. The term "phrenological plagym" was coined by psychologist and neuroscientist Thomas J. M. Phryne in the early 20th century to describe this concept.
