Dopamine induced learning

While watching the killer whales and dolphins perform at the San Diego waterworld, I wondered what motivates these animals to display such acquired skills. I understand that it is the food that they get which prompts such abnormal behavior. But where did the process of learning triggered in those primitive brains. I believe it is the Dopaminergic neurons that are responsible for the learning behavior. These neurons have a predictive error response, which means they give a good stimulus to the brain in a reward comes along. But if expected rewards are not obtained it causes depression. This is known as motivation to us. If we get good results in a job we get motivated to do it. If not we get depressed. So, logically we always do something which gives maximum reward, that is, we always try do something we are good at. Wikipedia article -- "In nature, we learn to repeat behaviors that lead to maximizing rewards. "
This is true even for animals. They repeat the behavior which rewards them (reward is food). This is the reason why these wild creatures can be made to jump through hoops, because their Dopamine gets triggered if they do.

Now, comes the philosophical angle to it. In Bhagvad Gita, Lord Krishna asks Arjun not to think about rewards and just do his job. Thee were innumerabl conjectures by many people over many years. Some say that it makes the job more efficient if there is no expectation of the outcome. Some say that it frees the mind from the sense of lust, greed and material gain. But I believe it might have a more profound connotation. It asks humans not to behave as an animal. This is of extreme importance. By refusing to accept the Dopamine induced reward system inherited from our beastly ancestry, we would be transcending to a higher level of consciousness.

interesting write...but dont forget the thrill factor, may be the
dolphins like to jump as well. we do well when appreciated (dopamine)
also, we will do well a job that we just enjoy doin (adrenaline +
pituitrin + others). emotions drive our actions, and going by this
arguement we can classify all actions into a spectrum of bases
hormones :)

Fastest way to send multiple drafts from gmail

People claim that the fastest way to send multiple email drafts is to use Gmail IMAP with email client like Outlook or Evolution or Thunderbird. But I have found this is not true. Because Thunderbird and Evolution etc. email clients treats the drafts as emails still to be edited. So it is not just simple select all and hit send. Each email draft has to be opened and sent separately. That is a lot of clicks and mouse movements, wasting precious time and energy. I have a better solution which involves minimum keystrokes and mouse usage. Efficiency booster technique for sending emails.
If someone is feeling adventurous and want to try it from the Gmail interface itself, here's how to do it in the fastest possible manner. It involves using the mouse once. Select the first draft. Gmail would open a new email box and put the cursor inside the box to write.Press TAB once to go the Send button.Press ENTER to send. Now Gmail sends it and the box is gone but the highlight goes to the last li…

How to join audio tracks smoothly in Audacity

Audio tracks can be mixed easily in full fledged video editors like kdenlive or Adobe Premiere but for mixing or joining audio they would not provide the amount of control that audio editors like Audacity provide. The example I am going to show today would demonstrate the range of tools in Audacity that allows us to control the waveform and to mold it to our desire.

Today I am going to take a small track like a small 1 min. clip of storm sound and make a long continuous sounding storm audio clip from it.

STEP 1 : Open file
Open the clip in Audacity.

STEP 2 : Removing unwanted audio portion
There is always unwanted sections of the audio that we have to discard. Select the portion of background noise or unwanted audio.


Press DELETE key.

STEP 3 : Duplicating the track
Now we make a copy of the entire waveform and paste it at the end of the track.

Select the SELECT tool (the one which looks like I). Then select the whole waveform and prss Ctrl+c. Now click approximately at the end of the…
