8. Herophilus – 335-280 BC Father of Anatomy Ventricles are seat of human intelligence Termed Spinal cord as caudal prolongation of the rhombencephelon "the neura that make voluntary motion possible have their origin in the cerebrum (enkephalos) and spinal marrow"
9. Ventricular Pneumatic doctrine brain functions were carried out in the cerebral ventricles by the psychic pneuma, or animal spirit, a sort of special and light substance endowed with the power to perform sensory, motor and mental activities
11. Ventricle the seat of Mind Soul could not be localized but mind could First ventricle the common sense Second – reason, thinking and wisdom Third – Memory Nemesius (circa 320), bishop of Emesa

23. Mesmer’s Tub Gathered around a large oaken tub filled with magnetized water, iron filings and glass, Mesmer's patients grasped rods, held hands and waited for healing to take effect.
24. Bioelectricity 1791 - Luigi Galvani publishes work on electrical stimulation of frog nerves 1809 - Luigi Rolando uses galvanic current to stimulate cortex
26. 1809 - Luigi Rolando Ablation studies in animal – cerebrum and cerebellum Stimulated animal cortex Conluded - cerebrum controlled voluntary body functions and the cerebellum controlled involuntary functions.

33. 1825 - Jean-BaptisteBouillaud Presents cases of loss of speech after frontal lesions from clinicopathological correlation. We cannot test speech in animal Frontal lobe has other higher function which differentiate from animal. By symptom we can localize the cerebral lesion. Cerebellum controlled equilibrium and station Frontal lobe and higher mental functions
34. Phinease Gage (1848) On 13th Sept 1848 a railroad worker hard working, diligent, reliable, responsible, intelligent, good humored, polite god fearing, family oriented foreman Following an explosion iron bar drove into frontal lobe 1. He becomes unreliable and fails to come to work and when present he is "lazy." 2. He has no interest in going to church, constantly drinks alcohol, gambles, and "whores about." 3. He is accused of sexually molesting young children. 4. He ignores his wife and children and fails to meet his financial and family obligations. 5. He has lost his sense of humour. 6. He curses constantly and does so in inappropriate circumstances. 7. Died of status epilepticus in 1861
41. 1870, Hitzig and Fritsch Electrically stimulated various parts of a dog's motor cortex. They observed that depending on what part of the cortex they stimulated, a different part of the body contracted. Then they found that if they destroyed this same small area of the cortex, the corresponding part of the body became paralyzed. This is how it was discovered that every part of the body has a particular region of the primary motor cortex that controls its movement.

45. Leyton SSF & Sherrington CS (1917).Observations on the excitable cortex of the chimpanzee, orang-utan and gorilla. Q J Exp Physiol11, 135–222. Figure 1. Motor maps of the gorilla cortex A, scale drawing of the left hemisphere of one of Leyton & Sherrington’s experiments on a gorilla (gorilla 1). The numbers and letters encode a wide range of different primary movements evoked by faradic stimulation. Eye movements (372–388) were generally evoked from an area further rostral from the motor cortex. Owing to lack of space, many motor effects were not plotted.
