The Brain

Our daily lives are filled with rhythmic movements, such as walking, sports, and dancing, but the mechanisms by which the brain controls rhythmic movements are poorly understood. In this review, we examine the literature on neuropsychological studies of patients with focal brain lesions, and functional brain imaging studies primarily using finger-tapping tasks. These studies suggest a close connection between sensory and motor processing of rhythm, with no apparent distinction between the two functions. Thus, we conducted two functional brain imaging studies to survey the rhythm representations relatively independent of sensory and motor functions. First, we determined brain activations related to rhythm processing in a sensory modality-independent manner. Second, we examined body part-independent brain activation related to rhythm reproduction. Based on previous literature, we discuss how brain areas contribute rhythmic motor control. Furthermore, we also discuss the mechanisms by which the brain controls rhythmic movements.

Yoga Meditation

Recent neuroimaging studies of brain function have led to an explosion of knowledge about psychological processes and states. In this paper functional brain imaging studies of Yoga meditation are reviewed. Tantra-based meditations activate frontal and occipital cortical regions involved in focused, sustained attention and visual imagery. The overall pattern of brain activation in Tantra-based meditations is similar to that of self-hypnosis but different from that of sleep onset. Pure consciousness, the ultimate aim of Vedanta-based meditation, also activates frontal cortical areas regulating focused attention but deactivates sensory areas involved in imagery. Functional brain imaging studies thus support the distinction between meditation with conceptual support and pure-consciousness meditation without conceptual support, a distinction that appears throughout Yoga meditation texts. Brain imaging investigations also explain how Yoga therapy may be helpful to those with anxiety disorders by reducing activity in brain regions linked to the processing of negative emotions.

A considerable body of evidence suggests the involvement of serotonin neurotransmission in the pathogenesis of panic disorder. Research on pathways and functions of tryptophan, an essential amino acid converted into serotonin, may advance our understanding of serotonergic actions in panic disorder and related phenomena. The investigative approaches in this field include manipulations of tryptophan availability as well as genetic association and functional brain imaging studies. In this review we examine the principle findings of these studies and propose further research directions.

This tutorial/review covers functional brain-imaging methods and results used to study language and reading disabilities. Although the main focus is on functional MRI and functional MR spectroscopy, other imaging techniques are discussed briefly such as positron emission tomography (PET), electroencephalography (EEG), magnetoencepholography (MEG), and MR diffusion imaging. These functional brain-imaging studies have demonstrated that dyslexia is a brain-based disorder and that serial imaging studies can be used to study the effect of treatment on functional brain activity.
