After the pressure waves travel through the hearing organ, they exit through a second flexible cover at the other end, the round window. This creates pressure changes at the oval window, a flexible cover over the opening of the fluid-filled hearing organ. In the hearing system, sound (which is simply changes in pressure in the air) enters the ear through the ear canal, which vibrates the eardrum and bones of the inner ear. When pressure moves the fluid inside these structures, the fluid moves the hairs, which creates electrical signals that the hearing and balance nerves then send to the brain for interpretation. Although the organs look different and have different functions, the way they work is quite similar.īoth the hearing and vestibular organs are fluid-filled tubes, containing small hairs that are sensitive to changes in pressure. The inner ear contains two main structures: the cochlea (the hearing organ) and the semicircular canals and otoliths (the vestibular and balance organs). What Causes Third Window Syndrome? The Inner Ear is a Pressure Detection System Read on to find out more about the symptoms, causes and treatments for this disorder. Fortunately, this group of disorders is often medically or surgically treatable. These abnormalities can lead to vestibular symptoms such as dizziness, imbalance and difficulty focusing the eyes, as well as hearing symptoms such as hearing loss and sensitivity to loud sounds. The most commonly recognized is superior semicircular canal dehiscence (SSCD), but there are other types. Third window syndrome describes a group of inner ear disorders that results from a leakage of pressure and/or fluid from the inner ear structures. Without outside references, a false memory is as real as a true memory to us.Third window syndrome: What it is and how it’s treated What is Third Window Syndrome? “Interestingly, sometimes people are more confident about false memories than true ones. Also, the false memories activated the same region as true memories,” Dr Liu said. “We found that a false memory interacts with a true memory just like a regular memory. They also found that the neural connections made during the formation of a genuine memory were practically identical to those made during the formation of a false memory - suggesting a physical basis for false-memory syndrome. Using this approach, the scientists were able to implant the false memory of being in a box where the mice were given electric shocks even when this did not actually happen. Pulses of light could be used to bring back genuine memories, as well as a false memory created by associating a true memory with the memory of a small but unpleasant electric shock. This allowed the researchers to study nerve connections in the “memory cells” of a part of the mouse brain called the hippocampus. The study, published in the journal Science, used specially bred mice with a photosensitive pigment in their brains that stimulates the recovery of a genuine memory when the animals are exposed to a certain kind of light stimulus. He added: “The technology we developed for this study allows us to dissect and even potentially to tinker with the memory process by directly controlling the brain cells.”
