Conscious And Unconscious Perception And How Flexibly The Brain Processes Images
Our brains process many more stimuli than we become aware of. Often images enter our brain without being noticed: visual information is being processed, but does not reach consciousness, that is, we do not have an impression of it…
New Microscope Decodes Complex Eye Circuitry
The properties of optical stimuli need to be conveyed from the eye to the brain. To do this efficiently, the relevant information is extracted by pre-processing in the eye. For example, some of the so-called retinal ganglion cells, which transmit visua…
Illuminating Neuron Activity
All our daily activities, from driving to work to solving a crossword puzzle, depend on signals carried along the body’s vast network of neurons. Propagation of these signals is, in turn, dependent on myriad small molecules within nerve cells – recepto…
Method Of Clustered Gene Expression Analysis May Lead To Glaucoma Prevention
Glaucoma is the second-most common cause of blindness in the US, and occurs due to loss of retinal ganglion cells and degeneration of the optic nerve. Although it is known that high levels of pressure within the eye predispose individuals to the develo…

Visual Prostheses: Symposium To Explore Combining Functional Endpoints And Objective Visual Measures For Clinical Trials
The National Eye Institute (NEI) and Food and Drug Administration (FDA) are sponsoring a conference to determine how functional vision-related endpoints for clinical trials of visual prostheses will be analyzed and correlated with objective measures of…
Curious Snapshot Of Powerful Retinal Pigment And Its Partners
Science fiction novelist and scholar Issac Asimov once said, “The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‘Eureka!’ but ‘That’s funny.’ ” This recently rang true for an international team of researchers whe…
Parts Of Brain Can Switch Functions
When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex, while sounds are p…
