Examining networks in the dog brain provides further insights into mammalian evolution
A study on canine brain networks reveals that during mammalian brain evolution, the role of the cingulate cortex, a bilateral structure located deep in the cerebral cortex, was partly taken over by the lateral frontal lobes, ...

Why does your life flash before your eyes near death?
Survivors of close calls with death often recall extraordinary experiences: seeing light at the end of a tunnel, floating outside their own bodies, encountering deceased loved ones or recapping major life events in an instant.

Electroencephalography
Electroencephalography (EEG) is the recording of electrical activity along the scalp produced by the firing of neurons within the brain. In clinical contexts, EEG refers to the recording of the brain's spontaneous electrical activity over a short period of time, usually 20–40 minutes, as recorded from multiple electrodes placed on the scalp. In neurology, the main diagnostic application of EEG is in the case of epilepsy, as epileptic activity can create clear abnormalities on a standard EEG study. A secondary clinical use of EEG is in the diagnosis of coma and encephalopathies. EEG used to be a first-line method for the diagnosis of tumors, stroke and other focal brain disorders, but this use has decreased with the advent of anatomical imaging techniques such as MRI and CT.
Derivatives of the EEG technique include evoked potentials (EP), which involves averaging the EEG activity time-locked to the presentation of a stimulus of some sort (visual, somatosensory, or auditory). Event-related potentials refer to averaged EEG responses that are time-locked to more complex processing of stimuli; this technique is used in cognitive science, cognitive psychology, and psychophysiological research.
