One study by Petr Janata found that there are tonality-sensitive areas in the medial prefrontal cortex, the cerebellum, the superior temporal sulci of both hemispheres and the superior temporal gyri (which has a skew towards the right hemisphere). [19] Hemispheric asymmetries in the processing of dissonant/consonant sounds have been demonstrated.
Alzheimer's disease is typically thought to affect high-level brain functioning (like memory) but can also have negative impacts on visual pre-attentive processing. [21] Some of the difficulties with social interaction seen in autistic individuals may be due to an impairment in filtration of pre-attentive auditory information. [ 14 ]
Representation of the stages of processing in a typical reaction time paradigm. Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations.
Unconscious cognition is the processing of perception, memory, learning, thought, and language without being aware of it. [1]The role of the unconscious mind on decision making is a topic greatly debated by neuroscientists, linguists, philosophers, and psychologists around the world.
A girl whispers to another girl. Whispering is generally used quietly, to limit the hearing of speech to those closest to the speaker; for example, to convey secret information without being overheard or to avoid disturbing others in a quiet place such as a library or place of worship.
In EEG, however, this distribution at the scalp does not mean the P600 is coming from that part of the brain; a 2007 study using magnetoencephalography (MEG) speculates that the generators of the P600 are in the posterior temporal lobe, behind Wernicke's area. [5] The P600 was first reported by Lee Osterhout and Phillip Holcomb in 1992. [6]
It has been suggested that one integral facet of brain dynamics underlying conscious thought is the brain's ability to convert seemingly noisy or chaotic signals into predictable oscillatory patterns. [2] In EEG oscillations of neural networks, neighboring waveform frequencies are correlated on a logarithmic scale rather than a linear scale. As ...
The middle ear plays a crucial role in the auditory process, as it essentially converts pressure variations in air to perturbations in the fluids of the inner ear. In other words, it is the mechanical transfer function that allows for efficient transfer of collected sound energy between two different media. [ 2 ]
