Lateral cephalometric radiograph, used for skull analysis Lateral cephalometric radiograph is a radiograph of the head taken with the x-ray beam perpendicular to the patient's sagittal plane. Natural head position is a standardized orientation of the head that is reproducible for each individual and is used as a means of standardization during ...
[266] [267] As brain size increased, this altered the size and shape of the skull, [268] from about 600 cm 3 in Homo habilis to an average of about 1520 cm 3 in Homo neanderthalensis. [269] Differences in DNA, gene expression, and gene–environment interactions help explain the differences between the function of the human brain and other ...
TMS uses electromagnetic induction to generate an electric current across the scalp and skull. [16] [17] A plastic-enclosed coil of wire is held next to the skull and when activated, produces a varying magnetic field oriented orthogonally to the plane of the coil. The changing magnetic field then induces an electric current in the brain that ...
Richard Caton discovered electrical activity in the cerebral hemispheres of rabbits and monkeys and presented his findings in 1875. [4] Adolf Beck published in 1890 his observations of spontaneous electrical activity of the brain of rabbits and dogs that included rhythmic oscillations altered by light, detected with electrodes directly placed on the surface of the brain.

[89] [93] Many fields of study contribute to our understanding of dinosaurs, including physics (especially biomechanics), chemistry, biology, and the Earth sciences (of which paleontology is a sub-discipline). [135] [136] Two topics of particular interest and study have been dinosaur size and behavior. [137]
[W 63] [210] Five months later, Strickland won a Nobel Prize in Physics "for groundbreaking inventions in the field of laser physics", becoming the third woman to ever receive the award. [210] [211] Prior to winning the award, Strickland's only mention on Wikipedia was in the article about her collaborator and co-winner of the award Gérard ...
