Opiates and opioid peptides carry out their regulatory effects mainly by inhibiting neuronal activity. At the cellular level, opioids block voltage-dependent calcium channels, activate potassium channels and inhibit adenylate cyclase, thus reducing neurotransmitter release. An increasing body of evidence indicates an additional opposite, stimulatory activity of opioids. The present review summarizes the potentiating effects of opioids on transmitter release and the possible cellular events underlying this potentiation: elevation of cytosolic calcium level (by either activating Ca2+ influx or mobilizing intracellular stores), blockage of K+ channels and stimulation of adenylate cyclase. Biochemical, pharmacological and molecular biology studies suggest several molecular mechanisms of the bimodal activity of opioids, including the coupling of opioid receptors to various GTP-binding proteins, the involvement of different subunits of these proteins, and the activation of several intracellular signal transduction pathways. Among the many experimental preparations used to study the bimodal opioid activity, the SK-N-SH neuroblastoma cell line is presented here as a suitable model for studying the complete chain of events leading from binding to receptors down to regulation of transmitter release, and for elucidating the molecular mechanism involved in the stimulatory effects of opioid agonists

Jenny’s history teacher always sets the temperature in her classroom very low. Jenny always shivers when she is in class because
lidiya [134]
1) This type of conditioning is called classical conditioning. We learned that Jenny is always associating her room as a very cold environment. Because of this, she starts to <em>anticipate</em> this coldness that she even starts to shiver before she enters the room. Associating two events together is part of classical conditioning.

2) For this item, the type of conditioning shown is called operant conditioning. Operant conditioning is defined as having a change in behavior because of a reinforcement or a punishment. In this case, Jake is met with a punishment in the form of the ticket that's why his behavior changed.

3) This item is also an example of classical conditioning. Because you really disliked the sheep's brain, you started changing your behavior towards it that even something only <em>similar</em> to the brain makes you react unpleasantly. Here, you associated the brain (or the sight of something similar) to your very unpleasant experience in biology.

4) This one is another example of operant conditioning. Here, instead of being punished, you are offered a reinforcement in the form of a compliment. Because of this compliment, you decided to continue your haircut. Thus, the reinforcement successfully influenced your "behavior".

There are <em><u>four types of neuroglia</u></em> found within the central nervous system:

<u>Astrocytes</u> :

It maintains the blood brain barrier and preserve the chemical environment by recycling ions and neurotransmitters.

<u>Oligodendrocytes</u> :

The myelinate axons in the central nervous system and provide an overall structural framework.

<u>Ependymal cells</u> :

The line ventricles (brain) and central canal (spine) and are involved in the production of cerebrospinal fluid.

<u>Microglia</u> :

It removes cell debris, wastes and pathogens via phagocytosis.
