OSSM Neuro Chapter 24 - Memory Systems

The retinal ganglion cells send information from the eye to the brain. There are two main types.

How does your brain know where a sound came from?

The eye is a simple but elegant organ which is fine tuned to focus light and create images on the retina.

Processing visual information by the brain starts with the axons that form the optic nerve.

A gene can't do anything by itself. It must be expressed and transcription is the first part of that process.

The retina is made of three main layers of cells: the photoreceptors detect light and connect to bipolar cells which connect to retinal ganglion cells that send information to the brain.

DNA is very stable, but damage or replication errors can lead to permanent mutations so numerous mechanisms have evolved to repair it.

The hair cells of the cochlea can convert the vibrations of a sound wave into an oscillating change in membrane potential.

In eukaryotes, mRNA goes through several processing steps before it can be translated into protein.

The LGN is an important relay between the retina and the visual cortex.

Recombination evolved as a mechanism to repair double-stranded breaks but it is also important for sexual reproduction.

One of the most important jobs of DNA is to be copied. Here is how that works.
