Neuroscientists have found cells in the visual cortex, the part of the brain that processes vision, whose sole job is to respond to differences in the position of the images transmitted from each eye to the brain.

These cells, called binocular neurons, are thought to be the key to seeing in three dimensions.

Can there be a neuroscience of plants, minus the neurons? First off, and at the risk of offending some of my closest friends,

Plants do not have neuron just as humans don t have flowers! But you don t need neurons in order to have cell to cell communication and information storage and processing.

Even in animals, not all information is processed or stored only in the brain. The brain is dominant in higher-order processing in more complex animals,

But while plants don t have neurons, plants both produce and are affected by neuroactive chemicals! For example, the glutamate receptor is a neuroreceptor in the human brain necessary for memory formation and learning.

While plants don t have neurons, they do have glutamate receptors and what s fascinating is that the same drugs that inhibit the human glutamate receptor also affect plants.

From studying these proteins in plants, scientists have learned how glutamate receptors mediate communication from cell to cell.

So maybe the question should be posed to a neurobiologist if there could be a botany of humans, minus the flowers!

Over the course of the 1970s, neuroscientists like Quik learned that the nicotine molecule fits into receptors for the neurotransmitter acetylcholine like a key into a lock.

The primary neurotransmitter that nicotine nudges is dopamine, which plays an important role in modulating attention, reward-seeking behaviors, drug addictions, and movement.

Or more specifically a neurotoxin produced by one type of blue-green algae that can develop in warm standing water.

Under these conditions one species of alga Anabaena flos-aquae produces a neurotoxin anatoxin-A which depolarizes and blocks acetylcholine receptors causing death in animals that drink the pond water.

The elk also showed signs they had struggled on the ground further supporting neurotoxin poisoning. Based on circumstantial evidence the most logical explanation for the elk deaths is that on their way back to the forest after feeding in the grassland the elk drank water from a trough containing toxins created by blue-green algae

and monitored individual neurons while the rats explored. The neurons they were watching lie in a part of the brain called the entorhinal cortex.

It sits in the lower part of the brain near its intersection with the brain stem. This is the perfect position for a mapmaker:

Â As a rat walked around the enclosure a neuron in the entorhinal cortex fired;

and the neuron fired again. When the team mapped out all the points in the enclosure that had lit up a particular neuron they found that these weren't just random signals:

those hot spots defined a grid of equilateral triangles laid side by side. The grid produced by each grid cell can serve as a basic map where the hot spots are like signposts.

while tiny microelectrodes monitored neurons in the entorhinal cortex. When Buffalo and her coworkers compared eye-tracking results to the electrode measurements they found that the monkeys like the rats were using neurons in the entorhinal cortex to construct a triangular grid they could superimpose on their environment.

Â Primates though are sophisticated more cartographers: the monkeys were able to activate their grid cells simply by looking around.

One of Buffalo's research interests is the early diagnosis of neurodegenerative diseases. Studies of brain changes in Alzheimer's disease in humans consistently show localized degeneration in the same parts of the entorhinal cortex where Buffalo found grid cells in monkeys.

We can begin to learn how neurons in the brain are processing information in flight and how sensory information is transformed into action Dickinson says.

Dopamine is the neurotransmitter that sends messages to the part of the brain that controls movement and coordination.

Their discoveries described in a paper published online today in Cell include identification of a molecule that protects neurons from pesticide damage.

For the first time we have used human stem cells derived from Parkinson's disease patients to show that a genetic mutation combined with exposure to pesticides creates a'double hit'scenario producing free radicals in neurons that disable specific molecular pathways that cause nerve-cell death

Next they reprogrammed all of these cells to become the specific type of nerve cell that is damaged in Parkinson's disease called A9 dopamine-containing neurons

--thus creating two sets of neurons--identical in every respect except for the alpha-synuclein mutation.

and mutant neurons to pesticides--including paraquat maneb or rotenone--created excessive free radicals in cells with the mutation causing damage to dopamine-containing neurons that led to cell death said Frank Soldner M d. research scientist in Jaenisch's lab

and co-author of the study. In fact we observed the detrimental effects of these pesticides with short exposures to doses well below EPA-accepted levels said Scott Ryan Ph d. researcher in the Del E. Webb Center

Having access to genetically matched neurons with the exception of a single mutation simplified the interpretation of the genetic contribution to pesticide-induced neuronal death.

when exposed to pesticides disrupt a key mitochondrial pathway--called MEF2C-PGC1ALPHA--that normally protects neurons that contain dopamine.

which mutant neurons from cell death induced by the tested pesticides. Since several FDA-approved drugs contain derivatives of isoxazole our findings may have potential clinical implications for repurposing these drugs to treat Parkinson's.

and the damage done to dopamine-containing neurons it does not exclude other mutations and pathways from being important as well.

#Neurons in face recognition center respond differently in autistic brainin what are believed to be the first studies of their kind Cedars-Sinai researchers recording the real-time firing of individual nerve cells in the brain found that a specific type of neuron in a structure called the amygdala

and process information about emotions said Ueli Rutishauser Phd assistant professor of neurosurgery and director of Human Neurophysiology Research at Cedars-Sinai and first author of an article in the Nov 20 issue of the journal Neuron.

The amygdala--which is critical for face recognition and processing of emotions--is thought to be one of the principal areas where dysfunction occurs

but this is the first time single neurons in the structure have been recorded and analyzed in patients with autism.

Researchers in Cedars-Sinai's Department of Neurosurgery and Department of Neurology with colleagues from the California Institute of technology and Huntington Memorial Hospital in Pasadena listened in

The research team then compared recordings from neurons in the patients with autism to recordings from neurons in patients who did not have led autism

which to the discovery that a specific type of neuron performed atypically in those with autism.

Different neurons respond to different aspects of a task. In the amygdala which is known to be important for emotional memory certain neurons fire

when a person looks at a whole face; another population responds when viewing parts of faces

In the two patients with autism whole-face neurons responded appropriately but the face-part neurons were much more active

when the patients were shown the mouth region compared to when they were shown the eyes. A subpopulation of neurons in these patients with autism spectrum disorder showed abnormal sensitivity to the mouth region.

The amygdala neurons appeared normal from an electrical point of view and the whole-face-sensitive neurons responded normally.

Thus the subset of face-part-sensitive neurons was specifically abnormal in autism Rutishauser said.

The article's senior author Ralph Adolphs Phd Bren Professor of Psychology and Neuroscience at Caltech said the study presents new insights into mechanisms underlying the symptoms of autism

and opens the door for further studies. Are there genetic mutations that lead to changes in this one population of neurons?

Do the cell abnormalities originate in the amygdala or are they the result of processing abnormalities elsewhere in the brain?

Observing the activity of single neurons in the human brain is very challenging and only rarely done

A collaboration of neuroscientists and neurosurgeons allows these rare opportunities to be used to advance knowledge of how the brain works.

and behavior and without direct human feedback neuroscientists have had to make assumptions when interpreting animal responses.

whether the human amygdala contained face-sensitive neurons said Adam Mamelak MD professor of neurosurgery and director of Functional Neurosurgery at Cedars-Sinai.

In an intracranial electroencephalogram (EEG) study each time a targeted neuron is active it fires an action potential--a chemical and electrical change that can be recorded for later analysis. Like never before the researchers can witness in human subjects

In one they recorded the activity of single neurons as patients'brains processed cues from facial expressions.
