Disruption of right prefrontal cortex by low-frequency repetitive transcranial magnetic stimulation induces risk-taking behavior.
Decisions require careful weighing of the risks and benefits associated with a choice. Some people need to be offered large rewards to balance even minimal risks, whereas others take great risks in the hope for an only minimal benefit. We show here that risk-taking is a modifiable behavior that depends on right hemisphere prefrontal activity. We used low-frequency, repetitive transcranial magne...
متن کاملLow-frequency transcranial magnetic stimulation for visual spatial neglect: a pilot study.
OBJECTIVE The aims of this study were to investigate the effects of low-frequency repetitive transcranial magnetic stimulation on patients with visual spatial neglect and to explore the potential mechanisms of visual spatial neglect. METHODS A total of 14 patients with prior stroke and visual spatial neglect were divided into a control group and a treatment group. The treatment group was expo...

OBJECTIVE To explore long-term effects on unilateral spatial neglect of low-frequency repetitive transcranial magnetic stimulation (rTMS) over the unaffected posterior parietal cortex. DESIGN Uncontrolled pilot study. SUBJECTS Two chronic-phase patients with left-sided unilateral spatial neglect from cerebral infarction. METHODS Six rTMS sessions were undertaken for 2 weeks. Each session ...
متن کاملThe effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) on the treatment of aphasia caused by cerebrovascular accident (CVA)
Background: Aphasia is a common outcome of Cerebrovascular Accident (CVA) in which clinical interventions have limited effectiveness. Some evidence suggests that noninvasive stimulation of the brain can have beneficial effects in the treatment of CVA induced aphasia. In patients with motor aphasia, repetitive Transcranial Magnetic Stimulation (rTMS) is used to facilitate long-term improvement i...
متن کاملThe Effect of 10 Hz Repetitive Transcranial Magnetic Stimulation of Posterior Parietal Cortex on Visual Attention
Repetitive transcranial magnetic stimulation (rTMS) of the posterior parietal cortex (PPC) at frequencies lower than 5 Hz transiently inhibits the stimulated area. In healthy participants, such a protocol can induce a transient attentional bias to the visual hemifield ipsilateral to the stimulated hemisphere. This bias might be due to a relatively less active stimulated hemisphere and a relativ...
