+Have you ever morphed your handwritten choice of A into a B when you were in school doing multiple-choice questions? Have you ever picked up a grocery, then put it back right after? My first grad school paper is on this topic - a change of mind. What happens in your brain when you have such a change of mind? Is switching your choice from A to B actually helpful in your next exam? Let me give you some answers in this blog!

+### The dataset:
+Between 2022 to 2024, I “raised” 5 rats in a maze where milk from various ports is always delivered in a specific order across 5 milk spouts. 4 of these spouts are located at the end of 4 long maze arms (1 meter each), extending from the center platform, leading to the home spout, the 5th milk spout. I wanted to see if they can figure this milk delivery pattern out. If so, what is the neural mechanism behind it?

 > This is a really fun one — the combination of climbing deep in the forest, Mt. Tam ridge meandering, descents on well-paved roads, and hiking alongside waterfalls gives you a full day of an assortment of Marin beauty. The elevation gain is around 4000 ft, but it’s spread out. Not too difficult.

-### General logistical items and notes:
+
 1. This will be a full day trip. Highly likely you will need to take the ferry back because of the cold weather at sunset or you’re simply too tired. We left the GGBridge at 9am and took the 5pm ferry back from Sausalito.
 2. Due to the long duration of the trip spanning morning and evening, diverse terrain and activities the trip contains, bringing layers is a must.
 3. Because the climbs are spread out, it is important to take breaks to prevent cramps.

 intro:
   - excerpt: 'I am a fifth year PhD student in the Joint Bioengineering program at UC Berkeley and UCSF, advised by Prof. [Loren Frank](https://franklab.ucsf.edu/) (UCSF). I study how the brain extracts relational structures from a vast amount of experiences. Prior to this, I was fortunate enough to have worked with Prof. [Michale Fee](https://feelaboratory.org/) and [Emily Mackevicius](https://emackev.github.io/) at MIT on songbird learning where I developed an algorithm for [tracking the same neuron](https://www.biorxiv.org/content/10.1101/2023.05.13.540658v2) across days in optical data. Both the work then and now at UCSF center around neuronal sequences and temporal aspect of our daily experiences. While living in San Francisco, breathing in the fog, I often wake up from melodies in my dream. These melodies are made into songs under the Local Field Potential project.'
