What did Lashley develop by purposely damaging the brains of rats?
How did Lashley develop the equipotentiality hypothesis? He trained rats in the correct route through a maze, then deliberately damaged their brains and observed that this did not inhibit their progress through the maze.
How did Lashley develop the equal potentiality hypothesis?
How did Lashley develop the equipotentiality hypothesis? He trained rats in the correct route through a maze, then deliberately damaged their brains and observed that this did not inhibit their progress through the maze. Giorgio memorizes the German poem “The Erlking” to recite in his eighth grade German class.
Why is it called neuroplasticity?
Plasticity refers to the brain’s malleability, which is defined as being “easily influenced, trained, or controlled.”1 Neuro refers to neurons, the nerve cells that are the building blocks of the brain and nervous system. Thus, neuroplasticity is when nerve cells change or adjust.
Who invented equipotentiality?
Equipotentiality – a notion developed by Karl Spencer Lashley (1890–1958) positing that all areas of the brain are equally able to perform a task.
What is the equipotential theory?
Equipotentiality is the theory that the brain has the capacity (in the case of injury) to transfer functional memory from the damaged portion of the brain to other undamaged portions of the brain. This hypothesis, put forward by Karl Spence Lashley, is part of his law of mass action.
Who started neuropsychology?
Brenda Milner is a renowned British-Canadian neuropsychologist known as «the founder of neuropsychology». She was born about 100 years ago, and as a Cambridge graduate, she started her research carreer of a neurobiologist and psychologist in 1940s.
Who discovered neuroplasticity?
The term “neuroplasticity” was first used by Polish neuroscientist Jerzy Konorski in 1948 to describe observed changes in neuronal structure (neurons are the cells that make up our brains), although it wasn’t widely used until the 1960s.
What is neuroplasticity in psychology?
Neuroplasticity can be viewed as a general umbrella term that refers to the brain’s ability to modify, change, and adapt both structure and function throughout life and in response to experience.

After this he went to Harvard, but was dissatisfied and from there became the director of the Yerkes Laboratory of Primate Biology in Orange Park, Florida.
What did Karl Lashley discover about the brain?
Lashley also discovered that even if a person has sustained a significant deficit, the brain has the potential to make up for it. Both of these discoveries were important leaps in scientific knowledge regarding the brain. Karl Lashley was a neuropsychologist who made very significant discoveries regarding memory and brain function.
