A regular slow wave theta rhythm can be recorded in the medial entorhinal cortex (MEC) of freely moving rats during voluntary behaviors and paradoxical sleep. Electrode penetrations normal to the cortical layers proceeding from the deeper to the more superficial layers reveal a continuous theta rhythm in layers IV-III (deep MEC theta rhythm) with an amplitude maximum in layer III, a null betwee...

this study briefly reviews the heart abnormalities in diverse intracranial pathologies, including strokes, spontaneous and traumatic subarachnoid hemorrhage and intracranial hemorrhage, and presents the results of a one-year prospective study of heart abnormalities in patients with moderate to severe head injuries and subarachnoid hemorrhage. different abnormalities such as: qt -interval, t -wa...

This paper deals with speech emotion analysis within the context of increasing awareness on wide application potential of affective computing. Unlike the most of works in the literature which mainly rely on classical frequency and energy based features along with a single global classifier for emotion recognition, we propose in this paper some new harmonic and Zipf based features for better spe...

The beneficial effects of musical training are not limited to enhancement of musical skills, but extend to language skills. Here, we review evidence that musical training can enhance reading ability. First, we discuss five subskills underlying reading acquisition-phonological awareness, speech-in-noise perception, rhythm perception, auditory working memory, and the ability to learn sound patter...

The lowest frequencies are delta. These are less than 4 Hz and occur in deep sleep and in some abnormal processes, also during ex-periences of "empathy state". Delta waves are involved with our ability to integrate and let go. It reflects unconscious mind. It is the dominant rhythm in infants up to one year of age and it is present in stages 3 and 4 of sleep. It tends to be the highest in ampli...
