Sentences with phrase «auditory cortex by»

Not exact matches

In addition to the asymmetry of auditory cortex activation for the processing of the original music, we showed that BOLD signals were modulated by alterations of the musical stimuli.

Thus, the right - lateralized auditory cortex activation was attributable to the specific features of the (mainly consonant and structured) original music and was not simply an unspecific response that could have been elicited by any sound in general.

A new study published in PLOS Computational Biology investigates how temporal acoustic patterns can be represented by neural activity within auditory cortex, a major hub within the brain for the perception of sound.

It is thought to be caused by a reorganisation of the brain's auditory cortex, so too many neurons respond to particular sound frequencies.

The analysis revealed that by 26 weeks of gestation, the primary auditory cortex was in a much more advanced stage of development than the nonprimary auditory cortex.

According to a study conducted by researchers from CNRS and Inserm at the Centre de Recherche en Neurosciences de Lyon (CNRS / Inserm / Université Claude Bernard Lyon 1), amusics exhibit altered processing of musical information in two regions of the brain: the auditory cortex and the frontal cortex, particularly in the right cerebral hemisphere.

«By diverting their attention away from sound, the participants» auditory cortex activity went down, and the signal we were measuring also went down.»

«This allows us to search for what parts of the brain are generally activated by auditory stimuli,» he says, «and to separate an auditory field — for example [the] primary auditory cortex from higher auditory fields.»

By looking at activation of different brain regions while test subjects were exposed to different listening conditions, Dr. Johnsrude's research has revealed that the early processing of sound, which occurs in a brain region called the primary auditory cortex, depends on higher - level linguistic knowledge encoded in other regions of the brain.

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).

We observed a negative relationship in controls in left auditory cortex [r (13) = -0.58, p = 0.037, Figure 2C, left], confirming a functional dependency between theta and gamma under physiological conditions, compatible with gamma activity being down - regulated by theta activity.

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).

When the scientists measured the electrical activity in the subjects» brains, they found that the brain's auditory cortex was stimulated by pictures associated with sounds, in less than 200 milliseconds.

By independently manipulating the grammaticality and auditory tonal working memory demands of nested atonal musical sequences, we found that grammatical violations of nested musical dependencies led to increased BOLD responses in the right inferior frontal gyrus (IFG) and bilateral anterior insular cortices (AIC), whilst increased auditory working memory demands led to enhanced responses in the bilateral middle frontal gyri (MFG) and inferior parietal lobules (IPL).
