DOCTRINES OF SPURZHEIM.

Two radical neuron doctrines

Two radical neuron doctrines must be distinguished--strong and weak. G&S direct much of their attack at the former--but the Churchlands only hold the latter. The weak radical neuron doctrine remains a serious possibility. G&S describe the radical neuron doctrine in a number of slightly different ways, and we think this hides an important distinction. On the one hand, the radical neuron doctrine...

Challenging the doctrines of JPEG steganography

The design of both steganography and steganalysis methods for digital images heavily relies on empirically justified principles. In steganography, the domain in which the embedding changes are executed is usually the preferred domain in which to measure the statistical impact of embedding (to construct the distortion function). Another principle almost exclusively used in steganalysis states th...

Drs. Gall and Spurzheim on the Structure of the Brain

medullary fibres may be easily traced to the cerebellum. This, indeed, was known to the older anatomists, who called it " processus cerebelli ad medullam oblongatam." In its course upwards, it meets with a mass or ganglion called corpus dentatum, which contains much brown matter, and is considered by Dr. S. a preparatory apparatus, destined to increase the medullary filaments which enter it. Fr...

Johann Gaspar Spurzheim: A Life Dedicated to Phrenology

Loved for his empathetic nature but admired for his analytical mind, Gaspar Spurzheim (1776-1832) was a prominent contributor to phrenology, a field of neuroscience focused on studying the shapes of the skulls in relation to the activity levels of certain functional areas of the brain. This curiosity about the connection between physical characteristics and brain function was seeded in the youn...
