Functional parcellation of the human cortex plays an important role in the understanding of brain functions. Traditionally, functional areas are defined according to anatomical landmarks. Recently, new techniques were proposed that do not require a priori segmentation of the cortex. Such methods allow functional parcellation by functional information alone. We propose here a data-driven approac...

The authorswould like to correct an error in the derivation of the formula for sliding-window covariance of pure sinusoidal signals that are phaselocked (i.e., when fluctuations are spurious). While the derivation of the second term of Eq. (2) correctly uses the product-to-sum trigonometric identity, there is a missing factor of 2 in the similar derivation of the first term of Eq. (2); i.e., af...

parkinson’s disease (pd) is a progressive neurological disorder characterized by tremor, rigidity, and slowness of movements. specific changes associated with various pathological attacks in parkinson’s disease can be indicated in causality interactions of the brain network from resting state fmri data. in this paper, we aimed to reveal the network architecture of the directed influence brain n...

background: there are two types of primary dysmenorrhea (spasmodic and congestive) which differ from each other in terms of the time of menstrual cycle outbreak, pain quality and other symptoms. the present study aimed to determine the effect of acupressure at the sanyinjiao point (sp-6) on severity of menstrual symptoms (primary outcome) and the duration of resting time as well as the number o...

Objectives: This study evaluates the effects of 8 weeks of resistance exercises on the expression of neurotrophins and Trk receptors in Alzheimer model male Wistar rats. Methods: For this purpose, 32 mature male Wistar rats with a mean weight of 230-280 g were chosen and divided into Alzheimer and Sham groups. The rats in the sham group received normal saline, while the ones in the Alzheimer g...
