SEM image of hair bundles atop hair cells in the chick utricle collected on the Helios NanoLab 650. The hair-cell bodies are not visible in this image, but project below the surface of the epithelium, each reaching down to contact a neuron. The hair bundle is a collection of stereocilia arranged in a staircase pattern. The sterocilia contain mechanosensitive transduction channels that pop open when the hair bundle is deflected by tilting of the head, or linear accelerations of the head in the horizontal plane. Activation of the transduction channels depolarizes the hair cell, which triggers the release of synaptic vesicles.

pyramidal cells against a blue Nissl counterstain, at 40x. View it large to see the really fine processes.
CRISPR/Cas9 engineering was used in mouse embryonic stem cells to insert a GFP tag in frame with the motor-neuron-specific transcription factor HB9. These cells were differentiated into motor neurons. The resulting motor neuron nuclei are labeled with the GFP reporter (green) and counterstained with antibodies against the neuronal marker Tuj1 (red).

Head and initial part of the body of an immature zebrafish, viewed from above (eyes at left). Neurons (white spots) send signals to the spinal cord and coordinate the body’s movement. Researchers are studying a subset of these neurons that help maintain balance and posture.

These neurons are derived from mouse embryonic stem cells. Red indicates cells making a protein called TH that is characteristic of the neurons that degenerate in Parkinson's disease. Green indicates a protein that's found in all neurons. Blue indicates the nuclei of all cells. Studying dopaminergic neurons can help researchers understand the origins of Parkinson's disease and could be used to screen potential new drugs.

SOMA is an amazing 28-foot tall creature, occupying a space about 40 x 25 feet at Unity Plaza in downtown Vallejo. Created by the Flaming Lotus Girls for Burning Man in 2009, the sculpture was brought to Vallejo recently for a 2-year visit.
Representing two neurons connected by an axon bridge, observers can interact by pressing several buttons causing the LED light display to fire communication over the bridge.

A newborn mouse cochlea (purple) grown in cell culture, and neurons (orange) that send information from the cochlea to the brain. The cochlea is the hearing organ of the inner ear. Researchers are using these miniature structures to learn how individual cell types work, and to test potential therapies for hearing loss.

A fluorescent microscopic image of neurons generated from human embryonic stem cells. The neuronal cell bodies with axonal projections are visible in red and the nuclei in blue. Some of the neurons have become dopaminergic neurons (yellow), the type of neurons that degenerate in people with Parkinson’s disease.

Soma, created by the Flaming Lotus Girls, captures the essence of a neuron. Spinning balls of fire act as nuclei within the dodecahedron cell bodies. Dendrites extend up into the sky and reach down to the earth, emitting constant flame and color changing light. Along her axon, extend eighteen individually controlled fire effects across the stainless steel arch with sequenced LEDs on the underside.

Mouse embryonic stem cells were allowed to form floating aggregates and then to adhere to the culture dish. With the right growth factors, they began to differentiate into neurons. Green = antibody detecting neural precursor protein nestin, Blue = nuclear stain, Red = antibody detecting tubulin protein found in neurons.
Total magnification is 40X. Taken in Anjen Chenn's lab.

A fluorescent microscopic image of hundreds of human embryonic stem cells in various stages of differentiation into neurons. Some cells have become neurons (red), while others are still precursors of nerve cells (green). The yellow is an imaging artifact that results when cells in both stages are on top of each other.
The image was taken in the lab of Guoping Fan at the University of California, Los Angeles.

Axons transmit information within the nervous system. Let me start with one of the central concepts of neuroscience, the neuron doctrine, first proposed by (Santiago Ramón y Cajal ): discrete cells make up the nervous system. These cells are neurons; they are made up of dendrites, soma, and axons. In general, information flows from axons to dendrites.
In my mental model of a neuron, dendrites are receivers or input devices, and it integrates excitatory or inhibitory inputs received from other neurons.
I think of the dendrite inputs as analog signals; they continuously vary over time. The soma is a central processor that controls the form and function of the neuron. The axons are analog to digital converters and transmitters. The axon initial segment produces a digital action potential ("spike") when the summation of the voltages within the neuron are above a threshold. The action potential is a one-tenth of a volt electrical signal that travels down an axon at speeds up to about 100 meters per second. Myelin sheaths cover many axons; this increases the speed a signal can travel down an axon. The myelinated axons make up the white matter of the brain. Also, signals go faster when the axon diameter is larger.
The function and form of axons varies, here are a few basic categories Figure 1.1, [Examples (A-F) of the rich...]. (www.ncbi.nlm.nih.gov/books/NBK10976/figure/A48/)

A me la neve fa scattare il neurone numero Uno (o Due…non ricordo mai quale è), comunque quello a cui si è fermata la crescita a tre anni, per intenderci.
Al primo fiocco di neve smette di ciucciarsi il dito e sgrana gli occhioni.
Al secondo fiocco comincia a saltellare intorno e gridare nevicanivicanevicanevica, e smette solo quando il neurone numero Due (o Uno…vabbè, l’altro) gli arriva uno scappellotto sulla testa.
Al terzo fiocco di neve ha già indossato berretto di lana con pon pon, giaccone, guanti, moon boot e dice ‘vado a fare le palate’.
Se i fiocchi sono più di sette, il neurone numero Uno (o Due, insomma quello lì) tira fuori lo slittino.
Questa mattina c’erano mille mila fiocchi di neve,
così il neurone-quello-lì ha cominciato a zampettare intorno e io con lui, abbiamo svegliato la casa, tirato giù dal letto l’altro neurone, più coniuge e figliuolo, ci siamo vestiti come palombari, alle 7,30 eravamo già per la strada, con il figliuolo a dire ‘mà, sei felice, eh? Però se nevica anche domani e mi svegli alle 6,00 posso picchiarti?’ che non è carino, secondo me.
Adesso ha smesso di nevicare, di fuori non c’è quasi traccia di neve, e il neurone-quello-lì è tutto abbacchiato, che sospira e suda dentro il giaccone.
‘Amemi’ fa tanta tenerezza, il neurone-quello-lì.
Speriamo che nevichi un altro pochettino, che non si può guardare, un neurone triste.
Poverino lui.
E poverina me, che sono vestita come una palombara, e qui dentro ci saranno 800°…
