How did the Industrial Revolution contribute to the study of the human brain?
-The rise of the therapeutic asylum or mental hospital aimed at helping and studying the mentally ill occurred around the time of the Industrial Revolution, marking the beginning of a scientific study of the human brain.
What was the 'neuron doctrine' and who is credited with its discovery?
-The 'neuron doctrine' is the idea that the brain is made up of individual cells, similar to the rest of the body. This was discovered by Spanish neuroscientist Santiago Ramón y Cajal after developing a method of staining brain tissue.
Who founded the first psychology lab and when was it established?
-German doctor Wilhelm Wundt founded the first psychology lab at the University of Leipzig in 1879, establishing psychology as a separate discipline from other sciences.
What is the significance of Sigmund Freud's work in the field of psychology?
