can fmri read your mind?

FMRI detects blood flow in the brain, giving an indirect measure of brain activity. Most fMRI studies to date have used the technology to pinpoint the parts of the brain involved in different cognitive tasks, such as reading or remembering faces.

Each hemisphere of the brain is dominant for other behaviors. ... Of course, these are generalizations and in normal people, the two hemispheres work together, are connected, and share information through the corpus callosum.

The frontal lobe is the part of the brain that controls important cognitive skills in humans, such as emotional expression, problem solving, memory, language, judgment, and sexual behaviors. It is, in essence, the “control panel” of our personality and our ability to communicate.

Binghamton University neuroscientists seem to think so. With brainwaves, when we see an image or read a word, our brains react and start to process the signal. It seems that each individual's response to the external stimulus is different and forms a unique pattern.

The part of the brain that is responsible for complex thinking is the Frontal Lobe—Located under the forehead, the frontal lobe controls reasoning, planning, voluntary movement, and some aspects of speech. The prefrontal cortex is the part of the frontal lobe right behind the forehead.

Key Points. Functional magnetic resonance imaging (fMRI) is now widely used in cognitive neuroscience to look for changes in neural activity that correlate with particular cognitive processes.

Typically, when people look up and to the right, they are lying or tapping into their imagination. When they look up and to the left, they are remembering or recalling something, tapping into the memory part of the brain.

In adults, certain brain regions prefer to look at faces and socially relevant things while other brain regions prefer to look at environments and objects, and study results revealed that many regions of the babies' visual cortex showed the same preferences.

An fMRI can detect these different magnetic qualities and can be used to create a dynamic (moving) 3D map of the brain, highlighting which areas are involved in different neural activities. ... Greater spatial resolution allows psychologists to discriminate between different brain regions with greater accuracy.

Temporal Lobe. The temporal lobes contain a large number of substructures, whose functions include perception, face recognition, object recognition, memory, language, and emotion.

In a paper publishing online this week in Biological Psychiatry, University of Wisconsin-Madison psychology researchers David Devilbiss and Craig Berridge report that Ritalin fine-tunes the functioning of neurons in the prefrontal cortex (PFC) - a brain region involved in attention, decision-making and impulse control ...

Brain scans have revealed that when your mind wanders, it switches into “autopilot” mode, enabling you to carry on doing tasks quickly, accurately and without conscious thought. Our autopilot mode seems to be run by a set of brain structures called the default mode network (DMN).

Humans Aren't The Only Animals That Are Self-Aware, New Study Suggests. ... "The key insight is that those animals capable of simulating their future actions must be able to distinguish between their imagined actions and those that are actually experience."

For the clearest evidence of Bayesian reasoning in the brain, we must look past the high‐level cognitive processes that govern how we think and assess evidence, and consider the unconscious processes that control perception and movement. ... “We really are Bayesian inference machines,” he says.

The cerebrum, the largest part of the human brain, is associated with higher order functioning, including the control of voluntary behavior. Thinking, perceiving, planning, and understanding language all lie within the cerebrum's control.

Key assumptions of the biological approach: There is a direct correlation between brain activity and cognition. Biochemical imbalances can affect behaviour. Brain physiology can affect behaviour. Behaviour can be inherited (as it is determined by genetic information)

The cerebral cortex is responsible for most "higher order" or intellectual brain functions such as thinking, reasoning, judging, planning, voluntary movement, and overall behavior. Injury to this area of the brain can impair judgment, cause dramatic personality change, and create problems with attention and focus.
