Please look first at my comment at the end about Appendix A1. Here are my proof corrections for 3, 4, 5, 7 ,8, 10, 11, 12, 14, A2 chapter 3 page 41 3.17a backward k_b should be k_d (same as forward) page 42 I wondered if it would be better to have a centered dot to indicate multiplication in 3.19 and 3.20. ie CaPump is a single variable but Ca0Pump is Ca0 * Pump I guess it might be difficult to use the centered dot whenever any multiletter variable is in the term. page 45 Ideal amplifier extra space between the closing parenthesis and i1. The latter begins a new equation. page 47 3.29b The last term is - instead of +. i.e V2/R2 - (V1... page 48 fig 3.6 Consider marking the currents and directions. page 54 last line before references. The ",j" should be a subscript i.e r_{j-1,j} General. I don't remember all my suggestions on the previous reading but I believe they overlap and extend the above. Chapter 4 page 56 4.3 missing the partial symbol in front of x^2 page 56 4 lines above 4.1.1 V/x = 0 should read partial V / partial x = 0 page 57 4.6 another missing partial symbol in front of x^2 in left hand side. page 59 4.7 minus sign in front of 2 in firt two equations. The third equation has no minus sign and is correct. (AQ2) eqn 4.8 is correct page 61 end of first line after 4.13a. There is no theta in the last expression on the line. it should be t + Delta t (AQ3) eqn 4.13b is correct page 62 line 3 from 4.2.1. Remove the "and linear" page 62 first line above 4.20 tau_m should be k. Or else tau_m = c/g page 67 first line after figure. replace "are" with "is". i.e method is readily demonstrated. page 70 first line after box. Question: is "artefactual" the correct spelling? page 73 Item 3 paragraph. The bold M should be replaced by bold J in 4 places. page 74 second line from bottom. Optionally replace DASPK with IDA. But then the url would have to be replaced as well. I believe my suggestions on the previous reading are worth considering. page 74 line 4. The superscript 6 should be superscript 5. page 77 third line from bottom. Perhaps the ohm should be normal font. page 81 shouldn't we refer to the analogous method discussion in chap 10? page 82 I think we had a new figure for that with the threshold marked in part c. But maybe it isn't worth trying to substitute it. page 88 4.2.2.2 Should we leave it as DASPK or call it IDA and also change the table of contents. I guess it is up to you whether and which of the substantive suggestions I made on the previous reading should we try to incorporate. chapter 5 in half a dozen places they use the word "biologic". I don't like it and if you don't either, let's have them change every occurrence to "biological". page 99 5.3.1.2 Syntax twice we refer to the "currently selected section". That makes a lot of sense but would "currently accessed section" be better because of consistency? page 104 5.5.1 line 7 "right circular cylinders" . I am willing to leave it at that but I always thought I had computed them as frusta. page 105 13 lines from bottom. The spacing around the -1 is bad. the -1 should be move to the left so n3d()-1 is clearly an expression and is set off from the following parenthetical statement) page 106 line 4 in fig 5.6. Could you look up frustum/frusta and verify it doesnt' have two r's or the r in a different place? page 111 3rd item in table 5.3. Should (10^6 Omega) be (MOmega)? page 122 5.7.2.1 6th line. fm = 1/2 pi tau_m is correct but I wonder if people will realize everything after the / is in the denominator. page 123 5 lines from bottom. Do you mind that "frequency" is on its own line due to wrapping? page 124 line 14. There is excessive space between http:// and www. page 124 line 17. remove space between k and Omega in the R_m equation. page 125 fig 5.13 and 5.14 nseg=1 label should be bold in three places. I noticed that area and ri are mentioned several times in a context where they look like range variables. Be aware that those are functions that take a relative position argument. chapter 7 page 162 16 lines from bottom. replace "updations" by "updates" two lines down from that the last word "and" should be normal roman type and the next line after that "buttons in the" should be normal roman type. page 164 last line in the box. I don't have moby dick with me but I believe the quote is missing a "to" and should read mystifications to tedious to detail." page 165 line 8 "but few" should read "but a few" page 167 item 2 second line "time = tentry..." the equal sign should be roman type (same as time) instead of font used for tentry. page 170 item 6 line 7 first word "from" replace by "to". page 173 the three items at bottom of page and on next e.g resets... and return. should be resets... and returns or reset...and return. Since item 3 already has "returns" I guess we should use resets... and returns performs... and returns returns... page 179 first line after box. "this is all easily" should read "this is more easily" or "this is all more easily". also are the commas correct in that sentence? chapter 8 page 186 item 5 line 1. The fi ligature in finitialize I believe should not be used in the typewriter font. Instead f and i should be separate. This problem occurs in several places and chapters and I wonder if it can be fixed all at once. page 191 line 8 "if more that one" the that should be changed to than. page 196 line 3. indent the fcurrent() page 197 line 4. indent the fcurrent() chapter 10 page 266 last line in box. I don't know what should replace the "at that". Maybe those two words should be deleted. page 269 10.1.1.3 line 6 syn.cp change to syn.capre page 271 line 9-11 from bottom. The sentence is incorrect. Did my previous proof reading suggest an alternative? In fact it adds to the diagonal but fails to add the off-diagonal term. page 272 10.1.2.1 line 1 replace use by uses page 279 last three lines of the code section are broken poorly. They should be // and add ... to the list ncl cell[20].axon ..., \ syn, threshold...weight) page 280 second block of code from bottom. eliminate the ".." in the three lines of the body. AQ2 x axis units are ms AQ2-AQ6 no units on y axis chapter 11 page 308 figure 11.1A Not all lines are present in diagram. ie. two missing from right circle to up and down left. page 313 line 2 from bottom. Too much space in "NEURON Main Menu" page 325 line 9 fi in Artificial should not be a ligature with that font. page 326 11.5.1.1 line 1 replace make with makes page 334 lines the last three xvalue lines have weird spacing. I wish it each could be on one line, but otherwise broken more in keeping with typewriter font. chapter 12 page 343 line 10 from bottom. 2*x is wrong. Suggest programs written for versions as far back as version 2 will work... page 344 another "biologic". I hope they can all be changed to biological. page 351 table of Built-in functions. The whole thing is pretty messed up due to their line wrapping vs our attempt at 4 columns. page 354 first line above 12.4.4 (objrefs, ... would be better as (objref, ...) ie delete the s page 356 12.4.7 line 5 instead of for (expr1; expr2; expr3) stmt use for (stmt1; expr2; stmt3) stmt page 356 10.4.7 line 6 instead of for var = expr1, expr2, expr3 stmt use for var = expr1, expr2 stmt page 361 last line. the fscan() is a header that is dangling here and should be on the next page. page 387 last listing. it would be nice to have that entire listing on the same page. page 390 lines 11-13 the stack printout should have a sequence of greater to less indentation. page 390 line 12 from bottom. delete the first word, "to" or else change to "to be". page 392 line 6. change smouse to mouse page 394 line 2 from bottom. indent page 397 lines 14-15 the \ should be at the end of line 14 and removed from line 15. (note that at the end of line 14 should look like ...", \ i.e I added space between the , and the \. Appendix A1 this has been botched to the extent that I have to recalculate all the expressions. Did I by any chance already do this in the previous proof reading. Appendic A2 page 406 line 10 change "having same" to "having the same"
