To make matters more challenging, Lappas decided at this early stage in the experiment to search for patterns not only in the auditory cortex but in other areas of the brain as well.

As a subject imagined hearing words, his auditory cortex lit up the screen in a characteristic pattern of reds and greens.

Recording the electrical activity of neurons directly from the surface of the brain, the scientists found that for a simple task, such as repeating a word presented visually or aurally, the visual and auditory cortexes reacted first to perceive the word.

The researchers used a technique called magnetoencephalography, which detects the firing of neurons as changes in the brain's magnetic field, to monitor the responses of the auditory cortex to the tones.

The existence of auditory responses in the occipital cortex of cataract - recovery patients, as observed in the study, therefore poses crucial questions regarding how these non-visual inputs coexist or even interfere with visual functions.

The team also found an association between the delayed development of the nonprimary auditory cortex in infancy and language delays in the children at age 2, suggesting that disruptions to this part of the brain as a result of premature birth may contribute to the speech and language problems often seen later in life in preemies, Monson said.

In fact, the parietal cortex is critical to auditory and tactile awareness as well as visual concentration, so Lavie's results are likely to have implications for a wide range of activities.

Sensory neurons, such as those in auditory cortex, on average respond relatively indiscriminately at the beginning of a new stimulus, but rapidly become much more selective.

As a result, the neurons in the auditory cortex form what is known as a tone maAs a result, the neurons in the auditory cortex form what is known as a tone maas a tone map.

A fetus starts to hear at about 24 weeks of gestation, as neurons migrate to — and form connections in — the auditory cortex, a brain region that processes sound, Stromswold explains.

The results show that brain activity in the auditory cortex continues without any problems, as long as we are subjected to sound alone.

Insight into the way the human auditory cortex manages multisensory effects could lead to better understanding of conditions that involve a deficit in audition, such as dyslexia.

The perception of music starts with specialised hair cells in the inner ear, which transmit sounds as electronic signals through the auditory pathway to the auditory cortex, where sounds are primarily recognised.

In trance, brain networks displayed notable reconfigurations, including increased connectivity in regions associated with internal thought (the default mode's posterior cingulate cortex) and cognitive control (dorsal anterior cingulate cortex and insula), as well as decreased connectivity within the brainstem and auditory pathway.

ASD participants showed a deficit in speech envelope tracking, as assessed by the BOLD signal, in a region of auditory cortex that overlapped with the region showing a global response deficit to the movie (Figures 1C, D).

The simultaneous EEG and fMRI recordings allowed us to explore how theta power fluctuations driven by the movie correlate with local synaptic activity in auditory cortex, as indexed by the BOLD signal (Magri et al., 2012; see Materials and Methods).

As both the theta - and gamma - informed MRI models showed significant effects in left auditory cortex during movie viewing, we assessed gamma and theta oscillations engagement during movie viewing (rest vs. movie) in each group in this region.

They found that when a participant preferred the piece attributed to a professional player, there was significantly more activity in the primary auditory cortex, as well as a region of the brain associated with pleasure and reward.

In an intriguing neuroimaging study of musical improvisation in classically trained pianists, Bengtsson et al. [13] found activations in the right dorsolateral prefrontal cortex, as well as premotor and auditory areas during improvisation.

Emotional sounds, such as crying and laughter also had a similar pattern of activity, with an area near the primary auditory cortex lighting up in dogs and humans.
