syn ap ses, the points where in for ma tion ex chan ges take place.
According to Professor Ramachandran, “the num ber of pos si ble per mu ta tions and com -
bi na tions of brain ac tiv i ty, in oth er words the num ber of brain states, ex ceeds the num ber of
el e men ta ry par ti cles in the known uni verse.” 84
A nerve cell in the brain pos sess es all the struc tures nec es sa ry to main tain for the cell’s me tab o lism,
for it to di gest pro teins and per form all the need ed func tions.
A neu ron has branched extensions, known as den drites. Dendrites’ great est func tion is to re ceive
elec tro mag net ic mes sa ges from oth er neu rons and to trans mit them to the cell body. Dendrites are rel a -
tive ly thick at the point where they leave the cell body, but then pro gres sive ly di vide in to tens, or even
hun dreds of branch es that then be come thin ner and thin ner. The num ber of den drites va ries, de pend -

Another ex ten sion de part ing from the neu ron is called the ax on, whose job is to car ry in for ma tion
to oth er neu rons. This in for ma tion as sumes the form of an elec tri cal cur rent. The brain con tains
de pots for the stor age of neu ro chem i cals, vesicles that re lease these chem i cals to car ry mes sa ges
to the next cell in the cir cuit. Neurons thus car ry in for ma tion along to the next neu ron by way of
ax ons. To put it an oth er way, den drites take the in for ma tion for ward ed from an oth er neu ron, and ax -
ons for ward it on to anoth er neu ron. Axons may ex tend for as long as a me ter, or else be just few tenths
of a mil li me ter.
How many dif fer ent types of neu rons are there in the brain? That ques tion has not yet been ful ly an -
swered, though there are es ti mat ed to be around fifty. Despite the dif fer en ces in their shapes, siz es,
