stimulation, interpretive responses included such feelings as déjà vu, the opposite sensation that everything was suddenly alien or absurd, senses of foreboding and fear, or sudden euphoria and exhilaration. Second was experiential responses described by his patients variously ashallucinatory “dreams” or “”falshbacks” or real events from the past, usually with unremarkable content. Jean Pierre Flourens- is a pioneer in experimental Neuroscience. Dissections are true experimental neuroscience. First to use Ablation as a technique. Developed chloroform as an anesthetic.

PSYC 316 – Systems & Theories of PsychologyExam 1 Study GuideLaw of Mass Action- the brain equipotentiality may sometimes be offset by the this. Whereby the efficiency of performance of an entire complex functions may be reduced in proportions to the extent of brain injury. Paul Broca- Chief of surgery at a pairs hospital. Supported Gall and phrenology.Well known for a chance discover. Worked on Tan. He identified the aphasia and expressive aphasia.Phrenology- Franz Gall as he convincingly demonstrated the general importance of the brain for all of the higher human functions, while also originating thepopular 19thcentury movement known as phrenology. Scientific contribution through anatomy and identified commissures, which are connections between the brain regions. Comparative Brain studies that animals with larger brains exhibited greater cognitive capacity. This claimed that the mind was realized through the brain. Who you are and what you want to become, comes from the brain. Difference in brain structure and characteristic. If you had more mass it would say your brain is enlarged. Proposed that cognitive functions were sourced in specific discrete brain locations. Extended this general idea to a pseudoscience that force causes Gall to be dismissed. Proposed craniology. A pseudoscience is the brain as “organ of the mind.” Could understand brain based on size of physical features. Indirect detection based on skull. Fortune teller. Gall did attempt to back his ideas with observations, but these were often subjective. Complex and redundant “faculties” or “organs”. Not content to stop at the assertion that higher functions were localized generally within the brain, Gall held that discrete psychological “faculties” were housed within specific parts of the brain. Puzzle box- cats had to escape from this box.Redundancy hypothesis- offers a related explanation, suggesting that each individual memory gets stored in several locations through the cortex, with the number increasing as the memory becomes better established and more widely associated with other memories.
