Marcel Just, Tom Mitchell, and colleagues at Carnegie Mellon University are conducting research on "thought identification" using fMRI. [1] Using machine learning techniques, they have been able to identify patterns of brain activation that are reliably associated to the concept of different objects.
One study on the effects of LSD demonstrated that the drug desynchronizes brain activity within the DMN; the activity of the brain regions that constitute the DMN becomes less correlated. [70] Psychotherapy – In PTSD, the abnormalities in the default mode network normalize in individuals who respond to psychotherapy interventions. [71] [60]
Proponents of the imprinted brain hypothesis argue that since it is uncertain if a woman's other and future children have and will have the same father, as well as the father generally having lower parental investment, it may be in the father's reproductive interest for his child to use more of the mother's resources than other children, while it may be in the mother's interest for a child to ...
The underconnectivity theory of autism posits that autistic people tend to have fewer high-level neural connections and less global synchronization, along with an excess of low-level processes. [31] Functional connectivity studies have found both hypo- and hyperconnectivity in brains of autistic people. [ 32 ]
The expression of some anatomical marker is taken to reflect neural activity. For example, the expression of immediate early genes is thought to be caused by vigorous neural activity. Likewise, the injection of 2-deoxyglucose prior to some behavioral task can be followed by anatomical localization of that chemical; it is taken up by neurons ...
Activity-dependent mechanisms influence neural circuit development and are crucial for laying out early connectivity maps and the continued refinement of synapses which occurs during development. [41] There are two distinct types of neural activity we observe in developing circuits -early spontaneous activity and sensory-evoked activity.
Heeger developed a class of circuit models, called Oscillatory Recurrent Gated Neural Integrator Circuits (ORGaNICs), that recapitulate many key neurophysiological and cognitive/perceptual phenomena including sensory processing and attention in visual cortex, working memory in prefrontal and parietal cortex, and premotor activity and motor ...
The book also has an index and notes section for easy reference and page finding. [3] [4] The book begins in its first chapter by discussing autism itself and how Grandin was treated as a child by medical professionals before autism was properly understood or considered a medical diagnosis.
