The first finding is that junctional rhythms are regular rhythms. This means that the time interval between beats stays constant. The next normal finding is a normal QRS. Since the impulse still travels down the bundle of His, the QRS will not be wide. Junctional rhythms can present with either bradycardia, a normal heart rate, or tachycardia. [9]
The neuroscience of rhythm refers to the various forms of rhythm generated by the central nervous system (CNS). Nerve cells, also known as neurons in the human brain are capable of firing in specific patterns which cause oscillations. The brain possesses many different types of oscillators with different periods.
Some types of neurons will fire rhythmically in the absence of any synaptic input. Likewise, brain-wide activity reveals oscillatory activity while subjects do not engage in any activity, so-called resting-state activity. These ongoing rhythms can change in different ways in response to perceptual input or motor output.
Rhythm is a strong repeated pattern of movement or sound. When individuals are preparing to tap out a rhythm of regular intervals (1:2 or 1:3) the left frontal cortex, left parietal cortex, and right cerebellum are all activated. With more difficult rhythms such as a 1:2.5, more areas in the cerebral cortex and cerebellum are involved. [16]
Brainwave entrainment, also referred to as brainwave synchronization or neural entrainment, refers to the observation that brainwaves (large-scale electrical oscillations in the brain) will naturally synchronize to the rhythm of periodic external stimuli, such as flickering lights, [1] speech, [2] music, [3] or tactile stimuli.
The right brain training works because of brain plasticity — the ability of your brain to change at any age based on your experiences. Twenty years ago, Dr. Merzenich pulled together a global ...
In the brain, it is believed that the right hemisphere better handles meter, while the left hemisphere better handles rhythm. Scientists have studied patients with brain lesions in their right temporal auditory cortex and realized that they were unable to "tap a beat or generate a steady pulse".
This rhythm occurs at frequencies similar to the mu rhythm, although alpha oscillations are detected over a different part of the brain. The left motor cortex, or BA4, is highlighted in green on this left lateral view of the brain. This is the area over which mu rhythms are detected bilaterally.
