5 0. Question 7 Action Potentials are the neurons output. Action potentials also known as spikes. These spikes are: Important energy source for the cells Binary (digital) representation of the neuronal information; each spike is either "all" ("") or "none" ("0") Although very important, we find them in very few nerve cells Analog representation of the neuronal information larger spikes are capable to transmit more information. Total / Question 8 Optogenetics is a new scientific method allowing: Coloring of different cell types with different colors Activation (or inactivation) of specific cells (that were /9

6 manipulated genetically) using light Changing the genetic code of neurons while recording from them Simulating very large cortical networks consisting of modeled neurons 0 Total / Question 9 The neuron doctrine based on the work of Ramon y Cajal is a theory suggesting: Action potentials are generated due to the opening of membrane ion channels The nervous system is constructed from discrete individual cells neurons Memories are created and saved in the brain The signal between cells passes through chemical synapses Total / Question 0 Choose the answer that corresponds to the correct order of values in A,B,C & D.

An action potential in the pre-synaptic cell triggers release of containing that spreads into the synaptic gap. in the post-synaptic cell recognize transmitter molecules and this may results in voltage change (the post synaptic potential). dendrite,vesicles,receptors,synapse,axon,neurotransmitters synapse,receptors,dendrite,vesicles,neurotransmitters,axon receptors,axon,dendrite,vesicles,neurotransmitters,synapse synapse,axon,dendrite,vesicles,neurotransmitters,receptors Total / Question The age of the modern Human (Homo sapiens Sapiens) is: 00,000 years,000 years 0,000 years,000,000 years 8/9
